My patches are based on v3.8-rc where OMAP hasn't been converted to
multiplatform.  But you are right, when the patches get into linux-next
it will cause problem for OMAP, since multiplatform is enabled for OMAP
on linux-next.  So should I base my patches on linux-next and fold a
fix for OMAP into the series?
