I know that Laxman has checked with the HW engineers, and they see no
reason to do this. I was originally worried about hung FIFOs preventing
an in-progress DMA from completely without the removed code, but according
to HW, that isn't a concern.

Olaf,
Can it be applied if it is OK to you?

Thanks,
Laxman
