[PATCH 8/16] drivers/infiniband/hw/cxgb3/iwch_cm.c: use WARN

From: Julia Lawall
Date: Sat Nov 03 2012 - 07:02:29 EST


From: Julia Lawall <Julia.Lawall@xxxxxxx>

Use WARN rather than printk followed by WARN_ON(1), for conciseness.

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

// <smpl>
@@
expression list es;
@@

-printk(
+WARN(1,
es);
-WARN_ON(1);
// </smpl>
