From: Greg Kroah-Hartman
Date: Thu Dec 10 2020 - 09:37:42 EST


From: Luo Meng <luomeng12@xxxxxxxxxx>

commit 855b69857830f8d918d715014f05e59a3f7491a0 upstream.

Fix to return a negative error code from the error handling case
instead of 0 in function i8042_setup_aux(), as done elsewhere in this
function.

Fixes: f81134163fc7 ("Input: i8042 - use platform_driver_probe")
