drivers/rtc/rtc-s3c.c: fix prototype for s3c_rtc_setaie()

2011-03-05T01:53:38Z

Fix s3c_rtc_setaie() prototype to eliminate the following compile warning: drivers/rtc/rtc-s3c.c:383: warning: initialization from incompatible pointer type (akpm: the rtc_class_ops.alarm_irq_enable() handler is being passed two arguments where it expects just one, presumably with undesired effects) Signed-off-by: Axel Lin Cc: Alessandro Zummo Cc: Ben Dooks Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/rtc/rtc-ds3232.c: fix time range difference between linux and RTC chip

2011-02-25T23:07:37Z

In linux rtc_time struct, tm_mon range is 0~11, tm_wday range is 0~6, while in RTC HW REG, month range is 1~12, day of the week range is 1~7, this patch adjusts difference of them. The efect of this bug was that most of month will be operated on as the next month by the hardware (When in Jan it maybe even worse). For example, if in May, software wrote 4 to the hardware, which handled it as April. Then the logic would be different between software and hardware, which would cause weird things to happen.

RTC: Re-enable UIE timer/polling emulation

2011-02-17T22:59:42Z

This patch re-enables UIE timer/polling emulation for rtc devices that do not support alarm irqs. CC: Uwe Kleine-König CC: Thomas Gleixner Reported-by: Uwe Kleine-König Tested-by: Uwe Kleine-König Signed-off-by: John Stultz

RTC: Revert UIE emulation removal

2011-02-17T22:59:41Z

Uwe pointed out that my alarm based UIE emulation is not sufficient to replace the older timer/polling based UIE emulation on devices where there is no alarm irq. This causes rtc devices without alarms to return -EINVAL to UIE ioctls. The fix is to re-instate the old timer/polling method for devices without alarm irqs. This patch reverts the following commits: 042620a018afcfba1d678062b62e46 - Remove UIE emulation 1daeddd5962acad1bea55e524fc0fa - Cleanup removed UIE emulation declaration b5cc8ca1c9c3a37eaddf709b2fd3e1 - Remove Kconfig symbol for UIE emulation The emulation mode will still need to be wired-in with a following patch before it will work.

RTC: Release mutex in error path of rtc_alarm_irq_enable

2011-02-17T22:59:22Z

On hardware that doesn't support alarm interrupts, rtc_alarm_irq_enable could return without releasing the ops_lock mutex. This was introduced in aa0be0f (RTC: Propagate error handling via rtc_timer_enqueue properly) This patch corrects the issue by only returning once the mutex is released.

drivers/rtc/rtc-proc.c: add module_put on error path in rtc_proc_open()
