Okay, yet I'd rather have a revert of commit c91134d91944 ("dmaengine: pxa_dma:
add support for legacy transition") , with the commit message saying:
    The conversion of the pxa architecture is now finished for all drivers, so this
    functions has fullfilled its purpose and can now be removed.

I have a similar patch in my internal tree, but yours can very well go in, as
long as it is a revert with a statement explaining why it is necessary now and
not before.

Cheers.
