[PATCH 4.4 52/86] net/mlx5: Fix driver load error flow when firmware is stuck

From: Greg Kroah-Hartman
Date: Mon May 18 2020 - 14:31:30 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")
