From: Johannes Berg <johannes.berg@intel.com> stable inclusion from stable-v5.10.102 commit b26ea3f6b7b0d9e7167c7c7c2d73328aadae3954 bugzilla: https://gitee.com/openeuler/kernel/issues/I567K6 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 4c29c1e27a1e178a219b3877d055e6dd643bdfda upstream. If we run into this error path, we shouldn't unlock the mutex since it's not locked since. Fix this in the gen2 code as well.
