[PATCH] wlcore: fix runtime pm imbalance in wl1271_tx_work

[Dinghao Liu]

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().
