watchdog: zx2967_wdt: Convert to use device managed functions and other improvements

2019-05-05T19:02:34+00:00

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 empty remove function - Use devm_add_action_or_reset() for calls to clk_disable_unprepare - Use local variable 'struct device *dev' consistently - Use devm_watchdog_register_driver() to register watchdog device Cc: Jun Nie Cc: Shawn Guo Signed-off-by: Guenter Roeck Acked-by: Shawn Guo Signed-off-by: Wim Van Sebroeck

watchdog: zx2967: explicitly request exclusive reset control

2017-09-09T18:18:43+00:00

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.
