[PATCH v2 0/2] dmaengine: at_hdmac: Regression fix and cleanup

[Peter Rosin]

Hi!

I found a regression in DMA handling on one of our SAMA5D3 boards.

While combing through the regressing commit, a found two unrelated
strange things. The first is the actually problematic change. The
second is a number of suspect defines, that I fail to see how they
can ever do any good.

Cheers,
Peter
