* drivers/rtc/rtc-mrst.c: use release_mem_region after request_mem_regionJulia Lawall2011-05-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | The memory allocated using request_mem_region should be released using release_mem_region, not release_region. The semantic patch that fixes part of this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1,E2,E3; @@ request_mem_region(E1,E2,E3) ... ?- release_region(E1,E2) + release_mem_region(E1,E2) // </smpl> [akpm@linux-foundation.org: use resource_size()] Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Alessandro Zummo <a.zummo@towertech.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* rtc, x86/mrst/vrtc: Fix boot crash in rtc_read_alarm()Feng Tang2011-04-071-3/+4
| | | | | | | | | | | | | | | | | | | Commit f44f7f96a20 ("RTC: Initialize kernel state from RTC") caused a boot regression on the MRST platform. The reason is that rtc_device_register() calls rtc_read_alarm() after that change, which function does not have all driver data set up yet. The rtc-mrst driver needs to call dev_set_drvdata() before rtc_device_register() gets called.

| * | mrst/vrtc: Avoid using cmos rtc opsFeng Tang2011-02-141-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we don't assign Moorestown specific wallclock init and ops function the rtc/persisent clock code will use cmos rtc for access, this will crash Moorestown in that the ioports are not present. Also in vrtc driver, should avoid using cmos access to check UIP status.

* | RTC: Convert rtc drivers to use the alarm_irq_enable methodJohn Stultz2011-02-031-26/+5
|/ | | | | | | | | | | | | | | | | | | Some rtc drivers use the ioctl method instead of the alarm_irq_enable method for enabling alarm interupts. With the new virtualized RTC rework, its important for drivers to use the alarm_irq_enable instead. This patch converts the drivers that use the AIE ioctl method to use the alarm_irq_enable method. Other ioctl cmds are left untouched. I have not been able to test or even compile most of these drivers. Any help to make sure this change is correct would be appreciated!
