| Subject: net: stmmac: Terminate FPE workqueue in suspend |
| |
| 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. |
