drivers/rtc/rtc-ab8500.c: use IRQF_ONESHOT when requesting a threaded IRQ
Lee Jones [Wed, 11 Jul 2012 21:02:16 +0000 (14:02 -0700)]
commit 3cfd16a551dc0c188160e1765168a04baf2d3198 upstream.

This driver's IRQ registration is failing because the kernel now forces
IRQs to be ONESHOT if no IRQ handler is passed.
