[PATCH 9/11] drivers/target/target_core_rd.c: trivial: use BUG_ON

From: Julia Lawall
Date: Tue Aug 02 2011 - 06:36:13 EST


From: Julia Lawall <julia@xxxxxxx>

Use BUG_ON(x) rather than if(x) BUG();

The semantic patch that fixes this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@ identifier x; @@
-if (x) BUG();
+BUG_ON(x);

@@ identifier x; @@
-if (!x) BUG();
+BUG_ON(!x);
// </smpl>
