Subject: [PATCH] gpio: remove explicit comparison with 0
Message-ID: <20190907173910.GA9547@SD>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
User-Agent: Mutt/1.10.1 (2018-07-13)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

No need to compare return value with 0. In case of non-zero
return value, the if condition will be true.

This makes intent a bit more clear to the reader.
"if (x) then", compared to "if (x is not zero) then".
