stable inclusion from stable-v5.10.108 commit 169add82d20130125df73f681377a047959e5378 bugzilla: https://gitee.com/openeuler/kernel/issues/I574A9
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 837d9e49402eaf030db55a49f96fc51d73b4b441 ]
This bug resulted in only the current mode being resumed and suspended when the PHY supported both fiber and copper modes and when the PHY only supported copper mode the fiber mode would incorrectly be attempted to be resumed and suspended.
Fixes: 3758be3dc162 ("Marvell phy: add functions to suspend and resume both interfaces: fiber and copper links.")
