Date: Tue, 9 Apr 2019 10:23:59 -0700 From: Guenter Roeck <linux@...ck-us.net> To: Wim Van Sebroeck <wim@...ux-watchdog.org> Cc: linux-watchdog@...r.kernel.org, linux-kernel@...r.kernel.org, Guenter Roeck <linux@...ck-us.net> Subject: [PATCH 21/23] watchdog: stpmic1_wdt: Use 'dev' instead of dereferencing it repeatedly 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.
