The struct fhci_regs (in drivers/usb/host/fhci.h) is basically a redefinition
of the struct qe_usb_ctlr (in arch/powerpc/include/asm/immap_qe.h).
The qe_usb_ctlr struct is preferrable once it uses accurately the registers'
names found in the Freescale's QUICC Engine Block Reference Manuals (QEIWRM.pdf
Rev.4.4 Chapter 19 for MPC836xE series and MPC8323ERM.pdf Rev.2 Chapter 36 for
MPC832xE series), making easier to map the FHCI device driver to the hardware
manual. Also, as the FHCI driver uses the USB Controller registers, the name
qe_usb_ctlr is a more precise representation of the hardware than fhci_regs.

Set state bits after submitting data urbs & command urbs, so we know
what is in flight. Clear data bits when the data urb is finished, clear
command bit when we see the status urb for the command. Finish the scsi
command after running both status and data completion handlers for the
command.
Add a cmd status logging function for debugging purposes. Hook it into
the error handler, so we see in the log what status a command is in
which the scsi layer wants cancel.

Stop reusing sense urbs, just allocate a fresh one each time and free it
when done.
Stop storing a sense urb pointer in the scsi request, all you can do
with it is misusing. For example requeuing the sense urb, then f*ck it
up by picking the wrong one in case tagged requests don't finish in the
same order you've submitted them. Also note that (not-yet supported)
task management ops don't have a scsi request in the first place.

This reverts commit ceb3f91fd5.
IMO the real bug is assigning status urbs to scsi requests. First there
is no such link in the non-stream case. Also there isn't nessesarely a
scsi request in the first place, for example when submitting task
management requests.
This patch just papers over the real bug and introduces different status
urb handling in the stream/non-stream case for no good reason.

This reverts commit e4d8318a85.
This patch makes uas.c call usb_unlink_urb on data urbs. The data urbs
get freed in the completion callback. This is illegal according to the
usb_unlink_urb documentation.
This patch also makes the code expect the data completion callback
being called before the status completion callback. This isn't
guaranteed to be the case, even though the actual data transfer should
be finished by the time the status is received.
Background: The ehci irq handler for example only know that there are
finished transfers, it then has go check the QHs & TDs to see which
transfers did actually finish. It has no way to figure in which order
the transfers did complete. The xhci driver can call the callbacks in
completion order thanks to the event queue. This does nicely explain
why the driver is solid on a (usb2) xhci port whereas it goes crazy on
ehci in my testing.

Merge tag 'regulator-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator fixes from Mark Brown:
"One small bug fix, plus a rename of all the ST Ericsson regulators in
the device tree since all the device trees had been written with
different names and some infelicities in the test proceedures meant
that the device tree code had apparently never actually been run
against the upstream device tree."

extcon_dev_unregister(info->edev) doest not free info->edev, we need to call

Add missing platform_set_drvdata() in gpio_extcon_probe(), otherwise calling
platform_get_drvdata in gpio_extcon_remove() returns NULL.
Also add missing free_irq call in gpio_extcon_remove().

Currently, the index of "Dock-desk" and "Dock-card" are the same.
Thus the latter one overrides the first one.
Then we have problem when calling extcon_find_cable_index() because
edev->supported_cable[7] only matches "Dock-card".

emc2103.c:463:12: warning: conf_reg may be used uninitialized in this function
by checking the return value from read_u8_from_i2c(). This fixes a real problem,
as conf_reg is really uninitialized if read_u8_from_i2c returns an error.

Key lookups may call read_smc() with a fixed-length key string,

1a77b127ae (OMAP : SPI : use devm_* functions) converted the SPI
device controller state to use devm_kzalloc(). Unfortunately, this
is used against an unbound struct device, which results in the
following when the device is bound to its driver:

If the GPIOs used by the MMCI driver are not registered yet when the driver is
probe()d, they can't be used. This happens if the mmci driver is probed before
the respective GPIO controller (e.g. on the LPC32xx EA3250 board, the PCA9532
GPIO controller would be initialized via DT after mmci). Therefore, we defer
mmci in this case.

Zero is a valid GPIO and shouldn't be handled as an error return code from
