There should be a pci_dev_put when breaking out of a loop that iterates
over calls to pci_get_device and similar functions.
This was fixed using the following semantic patch.

This patch (as1018) adds an unusual_devs entry for the JetFlash
TS1GJF2A. This device doesn't like read requests for more than 188
sectors. Setting max_sectors down to 64 is overkill, but at least
it will work without errors.

A recent patch added software synchronization during EHCI startup,
so ports aren't switched away from the companion controllers after
resets have started. This patch adds a short delay letting hardware
finish that port switching before any new resets begin ... so both
ends of that hardware race window are closed.

This patch (as1010) was written by both Kay Sievers and me. It solves
the problem of duplicated keys in USB uevent structures by refactoring
the uevent subroutines, taking advantage of the way the hotplug core
calls uevent handlers for the device's bus and for the device's type.
Keys needed for both USB-device and USB-interface events are added in
usb_uevent(), which is the bus handler. Keys appropriate only for
USB-device or USB-interface events are added in usb_dev_uevent() or
usb_if_uevent() respectively, the type handlers.
In addition, unnecessary tests for NULL pointers are removed as are
duplicated debugging log statements.

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.

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.

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.

I found that there is a off-by-one problem in the following code.
Version: 2.6.24-rc2
File: fs/sysfs/file.c:118-122
Function: fill_read_buffer
--------------------------------------------------------------------
count = ops->show(kobj, attr_sd->s_attr.attr, buffer->page);
sysfs_put_active_two(attr_sd);
BUG_ON(count > (ssize_t)PAGE_SIZE);
--------------------------------------------------------------------
Because according to the specification of the sysfs and the implement of
the show methods, the show methods return the number of bytes which would
be generated for the given input, excluding the trailing null.So if the
return value of the show methods equals PAGE_SIZE - 1, the buffer is full
in fact. And if the return value equals PAGE_SIZE, the resulting string
was already truncated,or buffer overflow occurred.
This patch fixes an off-by-one error in fill_read_buffer.

The CONFIG_SUSPEND changes in 2.6.23 caused a regression under certain
configuration conditions (SUSPEND=n, USB_AUTOSUSPEND=y) where all USB
device attributes in sysfs (idVendor, idProduct, ...) silently disappeared,
causing udev breakage and more.
The cause of this is that the /sys/.../power subdirectory is now only
created when CONFIG_PM_SLEEP is set, however, it should be created whenever
CONFIG_PM is set to handle the above situation. The following patch fixes
the regression.
