If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit bdb9bc78af6b8f1629e22396eb7a90473500f0c0 Author: Dinghao Liu <dinghao.liu@xxxxxxxxxx> Date: Fri Sep 3 15:35:43 2021 +0800 qlcnic: Remove redundant unlock in qlcnic_pinit_from_rom [ Upstream commit 9ddbc2a00d7f63fa9748f4278643193dac985f2d ] Previous commit 68233c583ab4 removes the qlcnic_rom_lock() in qlcnic_pinit_from_rom(), but remains its corresponding unlock function, which is odd. I'm not very sure whether the lock is missing, or the unlock is redundant. This bug is suggested by a static analysis tool, please advise.
