Looks like the use of this was removed when I moved things over to using
the generic IRQ framework, but I didn't fully clean up.

Can you update the changelog to something along the lines of:

"commit 672e302e3c (ARM: OMAP: use edge/level handlers from generic IRQ
framework) removed retrigger support in favor of using generic IRQ
framework.  This patch cleans up some unused remnants of that removal.

Thanks,

Kevin
