| Subject: rt2x00: do not mark device gone on EPROTO errors during start |
| |
| From: Stanislaw Gruszka <stf_xl@wp.pl> |
| |
| commit ed53ae75693096f1c10b4561edd31a07b631bd72 upstream. |
| |
| As reported by Exuvo is possible that we have lot's of EPROTO errors |
| during device start i.e. firmware load. But after that device works |
| correctly. Hence marking device gone by few EPROTO errors done by |
| commit e383c70474db ("rt2x00: check number of EPROTO errors") caused |
| regression - Exuvo device stop working after kernel update. To fix |
| disable the check during device start. |
