Subject: [PATCH] net: brcm80211: Delete unnecessary checks before two function calls
Date: Wed, 04 Feb 2015 19:40:23 +0000
Message-ID: <54D275A7.3050701@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>

From: Markus Elfring <elfring@users.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.
