6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiri Pirko <jiri@xxxxxxxxxx>
[ Upstream commit d749d901b2168389f060b654fdaa08acf6b367d2 ]
Firmware version query is supported on the PFs. Due to this
following kernel warning log is observed:
[ 188.590344] mlx5_core 0000:08:00.2: mlx5_fw_version_query:816:(pid 1453): fw query isn't supported by the FW
Fix it by restricting the query and devlink info to the PF.
Fixes: 8338d9378895 ("net/mlx5: Added devlink info callback")
