Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
