Subject: [PATCH] wlcore: fix runtime pm imbalance in wl1271_tx_work
Git-commit: 9604617e998b49f7695fea1479ed82421ef8c9f0
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430, bsc#1176741
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().
