From 09fb6d010a574334ec3959b2ba206d8247565c8e Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Wed, 10 Apr 2019 09:27:43 -0700 Subject: [PATCH] watchdog: tqmx86_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.
