5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 35fe2ad259a3bfca15ab78c8ffb5278cb6149c89 ]
There is no point in calling hid_hw_stop() if hid_hw_start() has failed.
There is no point in calling hid_hw_close() if hid_hw_open() has failed.
Update the error handling path accordingly.
