USB: fix usbtest halt check on big endian systems

2008-02-08T19:46:24+00:00

usbtest did not swap the received status information when checking for
a non-zero value and failed to discover halted endpoints on big endian
systems.

USB: FIx locks and urb->status in adutux (updated)

2007-11-28T21:58:34+00:00

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.

USB: fix usbled disconnect read race #2

2007-11-28T21:58:33+00:00

usbled has a race where show methods for attributes in sysfs can
follow a NULL pointer during disconnect. The correct ordering fixes
it.

USB: open disconnect race in usblcd

2007-10-25T19:18:46+00:00

this driver has a possible use after free due to a race when disconnect
and open handle intfdata without a lock.

USB: fix read vs. disconnect race in cytherm driver

2007-10-25T19:18:44+00:00

the disconnect method of this driver set intfdata to NULL before
removing attribute files. The attributes' read methods will happily
follow the NULL pointer. Here's the correct ordering.

USB: fix locking in idmouse

2007-10-25T19:18:44+00:00

Pete caused me to lock at buggy drivers in this respect. The idmouse has
a race between open and disconnect. This patch

- solves the open/disconnect race
- switches locking to mutexes
