watchdog: atlas7_wdt: Convert to use device managed functions and other improvements
Use device managed functions to simplify error handling, reduce source code size, improve readability, and reduce the likelyhood of bugs. Other improvements as listed below. 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 - Drop assignments to otherwise unused variables - Drop unnecessary braces around conditional return statements - Drop empty remove function - Use devm_add_action_or_reset() for calls to clk_disable_unprepare - Replace 'of_clk_get(np, 0)' with 'devm_clk_get(dev, NULL)' - Introduce local variable 'struct device *dev' and use it instead of dereferencing it repeatedly - Use devm_watchdog_register_driver() to register watchdog device - Replace shutdown function with call to watchdog_stop_on_reboot() Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@linux-watchdog.org>
