From 8a746c15f1cf59dc739db30f6fc220c55a6176d5 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Thu, 11 Nov 2021 15:10:03 +0100 Subject: [PATCH] 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 c0e9f3f4233e ("rt2x00: check number of EPROTO errors") caused regression - Exuvo device stop working after kernel update. To fix disable the check during device start.
