Analyze and fix the following issue in the Linux kernel code: USB: FIx locks and urb->status in adutux (updated)
Problem Details: 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_ki...
