rtc: use boolean values with device_init_wakeup()

2025-01-09T17:29:24+00:00

device_init_wakeup() second argument is a bool type. Use proper boolean values when calling it to match the type and to produce unambiguous code which is easier to understand.

rtc: Switch back to struct platform_driver::remove()

2024-11-10T21:58:28+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/rtc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

rtc: rc5t583: Convert to platform remove callback returning void

2023-03-17T22:03:18+00:00

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
