usb: writing_usb_driver free urb cleanup
Allright. As Greg KH suggested I split this big patch into smaller ones to
make the changes easier to review. Having no better idea how to split that I
split it on a 'patch per file' basis. All those patches clean redundant 'if' before
usb_unlink/free/kill_urb():
if (urb)
usb_free_urb(urb); /* unlink / free / kill */
I decided not to touch bigger 'if's like
if (urb) {
usb_kill_urb(urb);
usb_free_urb(urb);
urb = NULL;
}
as that would be probably too intrusive. One of patches also fixes
drivers/usb/misc/auerswald.c memleak I found when digging the code. All those
patches are against 2.6.19-rc4.
