Subject: [PATCH] ufs: unlock_super without lock
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2e006393ba5b599d9c43f94f8d8989e68131433e;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] ufs: unlock_super without lock

ufs_free_blocks function looks now in so way:
if (err)
 goto failed;
 lock_super();
failed:
 unlock_super();

So if error happen we'll unlock not locked super.
