[PATCH 6/8] arch/arm/mach-omap2/dpll3xxx.c: drop if around WARN_ON

From: Julia Lawall <Julia.Lawall at lip6.fr>

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>
