watchdog: da9062_wdt: Use 'dev' instead of dereferencing it repeatedly
Introduce local variable 'struct device *dev' and use it instead of dereferencing it repeatedly. Also replace 'ret = func(); return ret;' with 'return func();'. 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 Cc: Support Opensource <support.opensource@diasemi.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Steve Twiss <stwiss.opensource@diasemi.com> Signed-off-by: Wim Van Sebroeck <wim@linux-watchdog.org>
