From: Dan Carpenter Date: Mon, 20 Feb 2012 22:53:05 +0000 (-0500) Subject: ext4: remove an unneeded NULL check in __ext4_check_dir_entry() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4fda400360e6c15b9dea4351f2ad85845cdfda7e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ext4: remove an unneeded NULL check in __ext4_check_dir_entry() We dereference "bh" unconditionally a couple lines down to find "by->b_size". This function is never called with a NULL "bh" so I have removed the check.
