Subject: [PATCH] ARM: versatile: use BUG_ON where possible
In-Reply-To: <1352406191-14303-1-git-send-email-sasha.levin@oracle.com>

To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org
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/)
//
@@
expression e;
@@
- if (e) BUG();
+ BUG_ON(e);
//
