Subject[PATCH 5.13 012/223] net: stmmac: Terminate FPE workqueue in suspend
Date
From: Mohammad Athari Bin Ismail <mohammad.athari.ismail@intel.com>

[ Upstream commit 6b28a86d6c0bb02119f386ec2f56efde909e9bcb ]

Add stmmac_fpe_stop_wq() in stmmac_suspend() to terminate FPE workqueue
during suspend. So, in suspend mode, there will be no FPE workqueue
available. Without this fix, new additional FPE workqueue will be created
in every suspend->resume cycle.

Fixes: 5a5586112b92 ("net: stmmac: support FPE link partner hand-shaking procedure")
