From 9723a82a97df45c1e80730d554db4f45f0394c50 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Tue, 9 Apr 2019 10:23:49 -0700 Subject: [PATCH] watchdog: pm8916_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.
