5cc59c418fde9d02859996707b9d5dfd2941c50b is the first bad commit commit 5cc59c418fde9d02859996707b9d5dfd2941c50b Author: Alan Stern Date: Fri May 21 22:16:23 2021 -0400 USB: core: WARN if pipe direction != setup packet direction When a control URB is submitted, the direction indicated by URB's pipe member is supposed to match the direction indicated by the setup packet's bRequestType member. A mismatch could lead to trouble, depending on which field the host controller drivers use for determining the actual direction. This shouldn't ever happen; it would represent a careless bug in a kernel driver somewhere. This patch adds a dev_WARN_ONCE to let people know about the potential problem. Suggested-by: "Geoffrey D.
