From ed53ae75693096f1c10b4561edd31a07b631bd72 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Thu, 11 Nov 2021 15:10:03 +0100 Subject: rt2x00: do not mark device gone on EPROTO errors during start 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.
