[PATCH 2/20] staging: lustre: ldlm: ldlm_lock: remove unneeded null test before free

From: Julia Lawall
Date: Fri May 01 2015 - 15:47:10 EST


Kfree can cope with a null argument, so drop null tests.

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

// <smpl>
@@ expression ptr; @@

- if (ptr != NULL)
kfree(ptr);
// </smpl>
