This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Kevin Hilman <khilman@xxxxxx>
Subject: drivers/rtc/rtc-twl.c: fix threaded IRQ to use IRQF_ONESHOT
Requesting a threaded interrupt without a primary handler and without
IRQF_ONESHOT is dangerous, and after commit 1c6c6952 ("genirq: Reject
bogus threaded irq requests"), these requests are rejected. This causes
->probe() to fail, and the RTC driver not to be availble.
To fix, add IRQF_ONESHOT to the IRQ flags.
Tested on OMAP3730/OveroSTORM and OMAP4430/Panda board using rtcwake to
wake from system suspend multiple times.
