This patch (as1009) solves the problem of multiple registrations for
USB sysfs files in a more satisfying way than the existing code. It
simply adds a flag to keep track of whether or not the files have been
created; that way the files can be created or removed as needed.

Per the maintainer of the usbserial/sierra.c driver, the patch below adds
a new id to the list of supported cards for the sierra driver. Tested and
working for me on Fedora 8, kernel 2.6.23 and on the more recent sierra.c
available in
http://www.sierrawireless.com/resources/support/Software/Linux/v.1.2.6b(kernel2.6.21).zip
Hardware is a MiniPCI card in a Lenovo T61p.

Alan Stern:
I agree with your sentiment, but it would be better to solve this
problem without using local_irq_disable().

Two main issues fixed here are:
- An improper use of in-struct lock to protect an open count
- Use of urb status for -EINPROGRESS
Also, along the way:
- Change usb_unlink_urb to usb_kill_urb. Apparently there's no need
to use usb_unlink_urb whatsoever in this driver, and the old use of
usb_kill_urb was outright racy (it unlinked and immediately freed).
- Fix indentation in adu_write. Looks like it was damaged by a script.
- Vitaly wants -EBUSY on multiply opens.
- bInterval was taken from a wrong endpoint.

In commit acd2a847e7 usb_serial_generic_write()
disables interrupts when taking &port->lock which is also taken in
usb_serial_generic_read_bulk_callback() resulting in an inconsistent lock state
due to the latter not disabling interrupts on the local cpu. Fix that by
disabling interrupts in the latter call site also.

Add pci_enable_device() to aec62xx probe function

Original probe function tries to read from device's
PCI region 4 before calling ide_setup_pci_device().
Since the device is not enabled at this point,
on machines that have no firmware PCI initialization
(e.g. ASUS WL-700gE router), corresponding PCI BAR
is 0 and the following inb() causes a kernel oops.

There is a problem in some hardware where the kernel will stall for
35 seconds waiting for disks that don't exist. This patch will skip
waiting for the BSY-bit on IDE drives to go away if you set "hdx=noprobe"
as a kernel option and the disk is not marked as 'present' (like when
you set the geometry by hand).
If no noprobe-option is set the code will work (more or less) as the
original but if set the code will skip the ide_wait_not_busy() for
that drive. Even if there would be a drive there and it is still busy
afterwards it should not matter since it isn't probed for later.
The code also honors the MAX_DRIVES variable instead of assuming that
there will be two harddrives on the bus.

Plip passes a string "name" that is allocated on stack to
parport_register_device. parport_register_device holds the pointer to
"name" and when the registering function exits, it points nowhere.
On some machine, this bug causes bad names to appear in /proc, such as
/proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip
proc node is completely missing.
The patch also fixes documentation to note this requirement.
