From e0f49d270d9d04beec113aa7cfacac6bddcb5765 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 13 Jun 2020 19:12:24 +0200 Subject: [PATCH] ext4: delete unnecessary checks before brelse() The brelse() function tests whether its argument is NULL and then returns immediately. Thus remove the tests which are not needed around the shown calls. This issue was detected by using the Coccinelle software.
