Subject: [V2 net 04/11] net/mlx5: fw_reset: Don't try to load device in case PCI isn't working
Date: Sat,  5 Nov 2022 00:10:21 -0700	[thread overview]
Message-ID: <20221105071028.578594-5-saeed@kernel.org> (raw)
In-Reply-To: <20221105071028.578594-1-saeed@kernel.org>

From: Shay Drory <shayd@nvidia.com>

In case PCI reads fail after unload, there is no use in trying to
load the device.

Fixes: 5ec697446f46 ("net/mlx5: Add support for devlink reload action fw activate")
