If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit bc0d91d731ec4b80fc6caff3136c446a4c0e4af1 Author: Xiaoke Wang <xkernel.wang@xxxxxxxxxxx> Date: Fri Feb 18 21:59:45 2022 +0800 staging: wfx: fix an error handling in wfx_init_common() [ Upstream commit 60f1d3c92dc1ef1026e5b917a329a7fa947da036 ] One error handler of wfx_init_common() return without calling ieee80211_free_hw(hw), which may result in memory leak. And I add one err label to unify the error handler, which is useful for the subsequent changes.
