[PATCH AUTOSEL for 4.4 076/162] net/mlx5: Fix driver load error flow when firmware is stuck

From: Sasha Levin
Date: Sun Apr 08 2018 - 21:23:12 EST


From: Gal Pressman <galp@xxxxxxxxxxxx>

[ Upstream commit 8ce59b16b4b6eacedaec1f7b652b4781cdbfe15f ]

When wait for firmware init fails, previous code would mistakenly
return success and cause inconsistency in the driver state.

Fixes: 6c780a0267b8 ("net/mlx5: Wait for FW readiness before initializing command interface")
