Thanks for the quick fix, this is is fine with me as long as we
don't have other legacy users. At least I did not find any other
legacy users based on a quick grep.

We could now drop the legacy DMA init completely for omap4 and later.
But that would require patching the legacy DMA for the exported
functions.. So probably not doable for the -rc series and does not
solve the issue with other legacy IRQ users.

FYI, I posted a patch yesterday to drop the legacy init code
for twl6040 as the legacy omap4_pmic_init() is no longer used.
No need to change this patch though.
So unless somebody has better ideas for the fix for -rc series,
I'll queue this with the twl6040 code removal patch.
Regards,
Tony
