HID: u2fzero: properly handle timeouts in usb_submit_urb
[ Upstream commit 43775e6 ] The wait_for_completion_timeout function returns 0 if timed out or a positive value if completed. Hence, "less than zero" comparison always misses timeouts and doesn't kill the URB as it should, leading to re-sending it while it is active. Fixes: 42337b9 ("HID: add driver for U2F Zero built-in LED and RNG") Signed-off-by: Andrej Shadura <andrew.shadura@collabora.co.uk> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Sasha Levin <sashal@kernel.org>
