rtc: wm8350: Handle error for wm8350_register_irq

2022-03-23T18:58:38+00:00

As the potential failure of the wm8350_register_irq(), it should be better to check it and return error if fails. Also, it need not free 'wm_rtc->rtc' since it will be freed automatically.

rtc: wm8350: Remove unused to_wm8350_from_rtc_dev

rtc: rtc-wm8350: switch to using SIMPLE_DEV_PM_OPS

2013-04-30T01:28:32+00:00

Switch to using the SIMPLE_DEV_PM_OPS macro to declare the driver's pm_ops. It reduces code size. Signed-off-by: Jingoo Han Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Drivers: rtc: remove __dev* attributes.

2013-01-03T23:57:02+00:00

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

rtc: convert drivers/rtc/* to use module_platform_driver()

2012-01-11T00:30:53+00:00

This patch converts the drivers in drivers/rtc/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

RTC: Cleanup rtc_class_ops->update_irq_enable()

2011-03-09T19:23:37+00:00

Now that the generic code handles UIE mode irqs via periodic alarm interrupts, no one calls the rtc_class_ops->update_irq_enable() method anymore. This patch removes the driver hooks and implementations of update_irq_enable if no one else is calling it.

rtc: Suppress duplicate enable/disable of WM8350 update interrupt

2010-03-07T21:16:56+00:00

Unlike the wm8350-custom code genirq nests enable and disable calls so we can't just unconditionally mask or unmask the interrupt, we need to remember the state we set and only mask or unmask when there is a real change.
