2024-04-30	um: rtc: Convert to platform remove callback returning void	Uwe Kleine-König
	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 ignored (apart from emitting a warning) 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. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2021-02-12	um: add a pseudo RTC	Johannes Berg
	Add a pseudo RTC that simply is able to send an alarm signal waking up the system at a given time in the future. Since apparently timerfd_create() FDs don't support SIGIO, we use the sigio-creating helper thread, which just learned to do suspend/resume properly in the previous patch. For time-travel mode, OTOH, just add an event at the specified time in the future, and that's already sufficient to wake up the system at that point in time since suspend will just be in an "endless wait". For s2idle support also call pm_system_wakeup(). Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Richard Weinberger <richard@nod.at>
