From 08967c949c4ef4c3ddbd28d74f0fd5dc72e77825 Mon Sep 17 00:00:00 2001 From: Dinghao Liu Date: Thu, 21 Oct 2021 21:08:20 +0800 Subject: [PATCH] qlcnic: Remove redundant unlock in qlcnic_pinit_from_rom stable inclusion from stable-5.10.68 commit 9c98d2bd143420a26d3ba1b096326f28247a058d bugzilla: 182671 https://gitee.com/openeuler/kernel/issues/I4EWUH Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=9c98d2bd143420a26d3ba1b096326f28247a058d -------------------------------- [ 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.
