Subject[PATCH 6/16] drivers/infiniband/hw/cxgb4/cm.c: use WARN
Date
From: Julia Lawall <Julia.Lawall@lip6.fr>

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>

Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr>
