Subject: [PATCH] staging: wlan-ng: rewrite NULL comparison
Date: Tue, 5 Apr 2016 17:37:12 +0100 [thread overview]
Message-ID: <20160405163712.GA20559@cog.davos> (raw)
It is not necessary to compare explicitly to NULL. Rewrite if condition
as (!dev) or (dev) as suggested in Documentation/CodingStyle
