[PATCH] ARM: versatile: use BUG_ON where possible

[Sasha Levin]

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>
