41c8a48aa8 usb: fixes for v3.4-rc cycle
A few more fixes for v3.4-rc cycle.
 
 It includes a couple of fixes to the ordering of the methods in udc-core.c.
 Without these two patches, we will have issues when either unregistering a
 gadget driver (triggered with dummy_hcd only) or issuing a device-initiated
 disconnect through sysfs.
 
 There's also a fix on dummy_hcd to not call ->pullup() from udc_stop() because
 udc-core.c already handles that.
 
 A fix to MUSB as promised, to kill the compile warnings regarding deprecated
 interfaces. We are essentially dropping the __deprecated flag because it
 doesn't look like we will ever be able to live without it when we consider the
 amount of silicon issues we find on different MUSB instantiations.
 
 A couple of other fixes are also available, one adding the missing transceiver
 events to gpio_vbus and another adding a missing unregister call to MUSB's
 davinci glue layer.

320cd1e750 usb: gadget: udc-core: fix incompatibility with dummy-hcd
This patch (as1548) fixes a recently-introduced incompatibility
between the UDC core and the dummy-hcd driver.  Commit
8ae8090c82 (usb: gadget: udc-core: fix
asymmetric calls in remove_driver) moved the usb_gadget_udc_stop()
call in usb_gadget_remove_driver() below the usb_gadget_disconnect()
call.

As a result, usb_gadget_disconnect() gets called at a time when the
gadget driver believes it has been unbound but dummy-hcd believes
it has not.  A nasty error ensues when dummy-hcd calls the gadget
driver's disconnect method a second time.

To fix the problem, this patch moves the gadget driver's unbind
notification after the usb_gadget_disconnect() call.  Now nothing
happens between the two unbind notifications, so nothing goes wrong.

Here are the fixes I have queued for v3.4-rc cycle so far.
 
 It includes fixes on many of the gadget drivers and a few
 of the UDC controller drivers.
 
 For musb we have a fix for a kernel oops when unloading
 omap2430.ko glue layer, proper error checking for pm_runtime_*,
 fix for the ULPI transfer block, and a bug fix in musb_cleanup_urb
 routine.
 
 For s3c-hsotg we have mostly FIFO-related fixes (proper TX FIFO
 allocation, TX FIFO corruption fix in DMA mode) but also a couple
 of minor fixes (fixing maximum packet size for ep0 and fix for
 big transfers with DMA).
 
 For the dwc3 driver we have a memory leak fix, a very important
 fix for USB30CV with SetFeature tests and the hability to handle
 ep0 requests bigger than wMaxPacketSize.
 
 On top of that there's a bunch of gadget driver minor fixes adding
 proper section annotations, and fixing up the sysfs interface for
 doing device-initiated connect/disconnect and so on.
 
 All patches have been pending on the mailing list for quite a while
 and look good for your for-linus branch.

c85dcdac58 USB: gadget: storage gadgets send wrong error code for unknown commands
This patch (as1539) fixes a minor bug in the mass-storage gadget
drivers.  When an unknown command is received, the error code sent
back is "Invalid Field in CDB" rather than "Invalid Command".  This is
because the bitmask of CDB bytes allowed to be nonzero is incorrect.

When handling an unknown command, we don't care which command bytes
are nonzero.  All the bits in the mask should be set, not just eight
of them.

usb: gadget: eliminate NULL pointer dereference (bugfix)

This patch fixes a bug which causes NULL pointer dereference in
ffs_ep0_ioctl. The bug happens when the FunctionFS is not bound (either
has not been bound yet or has been bound and then unbound) and can be
reproduced with running the following commands:

$ insmod g_ffs.ko
$ mount -t functionfs func /dev/usbgadget
$ ./null

where null.c is:

#include <fcntl.h>
#include <linux/usb/functionfs.h>

int main(void)
{
	int fd = open("/dev/usbgadget/ep0", O_RDWR);
	ioctl(fd, FUNCTIONFS_CLEAR_HALT);

	return 0;

This patch removes the non-required spinlock acquire/release calls on
'queue->irqlock' from 'uvc_queue_next_buffer' routine.

This routine is called from 'video->encode' function (which translates to
either 'uvc_video_encode_bulk' or 'uvc_video_encode_isoc') in 'uvc_video.c'.
As, the 'video->encode' routines are called with 'queue->irqlock' already held,
so acquiring a 'queue->irqlock' again in 'uvc_queue_next_buffer' routine causes
a spin lock recursion.

During modprobe of gadget driver, pullup is called after
udc_start. In order to make the exit path symmetric when
removing a gadget driver, call pullup before ->udc_stop.

This is needed to avoid issues with PM where udc_stop
disables the module completely (put IP in reset state,
cut functional and interface clocks, and so on), which
prevents us from accessing the IP's address space,
thus creating the possibility of an abort exception
when we try to access IP's address space after clocks
are off.

f79a60b878 usb: fsl_udc_core: prime status stage once data stage has primed
- For Control Read transfer, the ACK handshake on an IN transaction
may be corrupted, so the device may not receive the ACK for data
stage, the complete irq will not occur at this situation.
Therefore, we need to move prime status stage from complete irq
routine to the place where the data stage has just primed, or the
host will never get ACK for status stage.
The above issue has been described at USB2.0 spec chapter 8.5.3.3.

- After adding prime status stage just after prime the data stage,
there is a potential problem when the status dTD is added before the data stage
has primed by hardware. The reason is the device's dTD descriptor has NO direction bit,
if data stage (IN) prime hasn't finished, the status stage(OUT)
dTD will be added at data stage dTD's Next dTD Pointer, so when the data stage
transfer has finished, the status dTD will be primed as IN by hardware,
then the host will never receive ACK from the device side for status stage.

- Delete below code at fsl_ep_queue:
       /* Update ep0 state */
       if ((ep_index(ep) == 0))
               udc->ep0_state = DATA_STATE_XMIT;
the udc->ep0_state will be updated again after udc->driver->setup
finishes.

It is tested at i.mx51 bbg board with g_mass_storage, g_ether, g_serial.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

 |
 |    __init, __initdata and __exit tags have have been removed from
 |    various files to make it possible for gadgets that do not use
 |    the __init/__exit tags to use those.
 obviously missed (at least) this case leading to a section mismatch in
 g_ffs.c when compiling with CONFIG_USB_FUNCTIONFS_ETH enabled.

410235fd4d TTY: remove unneeded tty->index checks
Checking if tty->index is in bounds is not needed. The tty has the
index set in the initial open. This is done in get_tty_driver. And it
can be only in interval <0,driver->num).

So remove the tests which check exactly this interval. Some are
left untouched as they check against the current backing device count.
(Leaving apart that the check is racy in most of the cases.)

2f16669d32 TTY: remove re-assignments to tty_driver members
All num, magic and owner are set by alloc_tty_driver. No need to
re-set them on each allocation site.

pti driver sets something different to what it passes to
alloc_tty_driver. It is not a bug, since we don't use the lines
parameter in any way. Anyway this is fixed, and now we do the right
thing.

30e9eb190f usb/gadget/pch_udc: Fix compile error
Greg's e-mail address was old. So, I resend it.

Though I've tested this patch,
http://marc.info/?l=linux-usb&m=132825305710285&w=2,
I've received the following reports.
http://kisskb.ellerman.id.au/kisskb/buildresult/5771890/
http://kisskb.ellerman.id.au/kisskb/buildresult/5771905/

So, I added header file for these symbols.
Using this patch, this compile error must be disappeared.

85b4b3c8c1 usb: gadgetfs: return number of bytes on ep0 read request
A read from GadgetFS endpoint 0 during the data stage of a control
request would always return 0 on success (as returned by
wait_event_interruptible) despite having written data into the user
buffer.
This patch makes it correctly set the return value to the number of
bytes read.

2a5be8783e Allocate correct size (portably) in drivers/usb/gadget/f_midi.c::f_midi_bind()
As the coverity checker puts it:

"Passing argument "sizeof (midi_function) /*8*/" to function "kcalloc"
and then casting the return value to "struct usb_descriptor_header **"
is suspicious. ... In this particular case sizeof(struct
usb_descriptor_header **) happens to be equal to sizeof(struct
usb_descriptor_header *), but this is not a portable assumption."

I believe we really do intend to use 'sizeof(*midi_function)' here, so
this patch makes that change.

This patch changes the ARCH name to "ARCH_S3C24XX" for Samsung
S3C2410, S3C2412, S3C2413, S3C2416, S3C2440, S3C2442, S3C2443,
and S3C2450 SoCs so that we can merge the mach-xxx directories
and plat-s3c24xx dir. to just one mach-s3c24xx for them.

I think this should be sent to upstream via samsung tree because
this touches many samsung stuff.
