Subject: [PATCH 10/22] watchdog: da9055_wdt: Use 'dev' instead of dereferencing it repeatedly
Date:   Mon,  8 Apr 2019 12:38:34 -0700
Message-Id: <1554752326-13319-11-git-send-email-linux@roeck-us.net>
In-Reply-To: <1554752326-13319-1-git-send-email-linux@roeck-us.net>
References: <1554752326-13319-1-git-send-email-linux@roeck-us.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Introduce local variable 'struct device *dev' and use it instead of
dereferencing it repeatedly.

The conversion was done automatically with coccinelle using the
following semantic patches. The semantic patches and the scripts
used to generate this commit log are available at
https://github.com/groeck/coccinelle-patches
