Subject: [PATCH 1/1] SPI-txx9: Deletion of an unnecessary check before the function call "clk_disable"
Date: Sat, 29 Nov 2014 18:40:28 +0100 [thread overview]
Message-ID: <547A050C.5040906@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>
From: Markus Elfring <elfring-Rn4VEauK+AKRv+LV9MX5uipxlwaOVQ5f@public.gmane.org>

The clk_disable() 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.
