5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Thompson <davthompson@xxxxxxxxxx>
[ Upstream commit d6c30c5a168f8586b8bcc0d8e42e2456eb05209b ]
The mlxbf_gige_open() routine starts the PHY as part of normal
initialization. The mlxbf_gige_open() routine must stop the
PHY during its error paths.
Fixes: f92e1869d74e ("Add Mellanox BlueField Gigabit Ethernet driver")
