Sakari Ailus 8a751ccf82 media: v4l2-ctrls: Don't reset handler's error in v4l2_ctrl_handler_free() ... commit 5a0400aca5 upstream. It's a common pattern in drivers to free the control handler's resources and then return the handler's error code on drivers' error handling paths. Alas, the v4l2_ctrl_handler_free() function also zeroes the error field, effectively indicating successful return to the caller. There's no apparent need to touch the error field while releasing the control handler's resources and cleaning up stale pointers. Not touching the handler's error field is a more certain way to address this problem than changing all the users, in which case the pattern would be likely to re-emerge in new drivers. Do just that, don't touch the control handler's error field in v4l2_ctrl_handler_free().
