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.
