Yes, Linus W has already queued some patches for gpio-omap on the
for-next branch of his linux-gpio tree [1] that solves this issue.

Take a look to commit b4419e1a ("gpio/omap: auto request GPIO as input
if used as IRQ via DT") although this patch depends on others so you
should merge the whole branch to make it work.

Linus, are you still planing to send this patches as fixes for the
v3.11 -rc cycle or did you decide to wait for v3.12?
