Subject: [PATCH] ARM: versatile: use BUG_ON where possible
Date: Thu,  8 Nov 2012 15:23:11 -0500	[thread overview]
Message-ID: <1352406191-14303-9-git-send-email-sasha.levin@oracle.com> (raw)
In-Reply-To: <1352406191-14303-1-git-send-email-sasha.levin@oracle.com>

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>
