Subject: ext3: drop if around WARN_ON
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4789775477718983b6f8c604a809b950c6a10052;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ext3: drop if around WARN_ON

Just use WARN_ON rather than an if containing only WARN_ON(1).

A simplified version of the semantic patch that makes this transformation
is as follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e;
@@
- if (e) WARN_ON(1);
+ WARN_ON(e);
// </smpl>
