* Kevin Hilman <khilman at ti.com> [120629 07:08]:
> commit 99b59df0 (ARM: OMAP3: PM: fix shared PRCM interrupt leave
> disabled at boot) added IRQ_NOAUTOEN to the PRCM interrupt so it could
> be enabled later if needed.  However, this commit was partially undone
> when merging the IO daisy chain rework in 9a17d88e (Merge tag
> 'omap-devel-c-for-3.6' of
> git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into
> devel-pm
> 
> This patch adds back the IRQ_NOAUTOEN fix that was removed by the
> merge resolution.
> 
> This also fixes the following boot-time warning that showed up after
> merging the IO daisy chain rework:
