[PATCH] rtc class locking bugfixes
I got a lockdep warning when running "rtctest" so I though it'd be good
to see what was up.
- The warning was for rtc->irq_task_lock, gotten from rtc_update_irq()
by irq handlerss ... but in a handful of other cases, grabbed without
blocking IRQs.
- Some callers to rtc_update_irq() were not ensuring IRQs were blocked,
yet the routine expects that; make sure all callers block IRQs.
It would appear that RTC API tests haven't been part of anyone's kernel
regression test suite recently, at least not with lockdep running.
