Subject: [PATCH] net: brcm80211: Delete unnecessary checks before two function
 calls

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 4 Feb 2015 20:28:49 +0100

The functions brcmu_pkt_buf_free_skb() and usb_free_urb() test whether
their argument is NULL and then return immediately. Thus the test around
the call is not needed.
