Subject: [PATCH 1/1] video: fbdev-OMAP2: Deletion of unnecessary checks before the function call "i2c_put_adapter"
Date: Sun, 23 Nov 2014 14:14:10 +0100 [thread overview]
Message-ID: <5471DDA2.1060000@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 23 Nov 2014 14:07:22 +0100
The i2c_put_adapter() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
