If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 95bbc68394c5a800f2f6b6b529afe594fe19dfb5 Author: Dinghao Liu <dinghao.liu@xxxxxxxxxx> Date: Wed May 20 20:42:38 2020 +0800 wlcore: fix runtime pm imbalance in wl1271_tx_work [ Upstream commit 9604617e998b49f7695fea1479ed82421ef8c9f0 ] There are two error handling paths in this functon. When wlcore_tx_work_locked() returns an error code, we should decrease the runtime PM usage counter the same way as the error handling path beginning from pm_runtime_get_sync().
