[PATCH] ARM: integrator: use BUG_ON where possible

From: Sasha Levin
Date: Thu Nov 08 2012 - 15:24:54 EST


Just use BUG_ON() instead of constructions such as:

if (...)
BUG()

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

// <smpl>
@@
expression e;
@@
- if (e) BUG();
+ BUG_ON(e);
// </smpl>
