* rtc: pcf50633: manage RTC alarm "pending" flagWerner Almesberger2009-12-16
| | | | | | | | | | | | | | | | Add setting and clearing of the "pending" flag of the RTC alarm. The semantics follow the UEFI specification 2.2 available at http://www.uefi.org/specs/, i.e., the "pending" flag is cleared by disabling the alarm, but not by any other condition (such as the passing of time, a successful wakeup, or setting of a new alarm.)

* mfd: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen2009-12-13
| | | | | | | | | | | | | Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata.

* drivers/rtc/rtc-pcf50633.c: fix use after free in pcf50633_rtc_probe()Dan Carpenter2009-12-01
| | | | | | | | | | | | "rtc" is freed and then dereferenced on the next line. This patch fixes that.

* rtc: pcf50633: consider alrm->enable in pcf50633_rtc_set_alarmWerner Almesberger2009-11-12
| | | | | | | | | | | | | | | According to Documentation/rtc.txt, RTC_WKALM_SET sets the alarm time and enables/disables the alarm. We implement RTC_WKALM_SET through pcf50633_rtc_set_alarm. The enabling/disabling part was missing.
