: [PATCH 2/2] OMAP2+: GPIO: move late PM out of
interrupts-disabled idle path

We cannot do a get_sync() from ISR context, right?
Right, but we *should* be able to. ;)
I'm still trying to craft a good description of this
problem

Currently, we wait until late in the idle path where interrupts are
disabled to do runtime-PM-like management for certain special-case
devices like GPIO

I'm still trying to craft a good description of this problem so I can
argue better for it on linux-pm.
Until then...
A bit of a hack, but
