In fact, I am not sure it's the best solution. I have noticed that there is a
conflict with a patch sent by Nicolas (dmaengine: at_hdmac: extend hardware
handshaking interface identification) which is already in Vinod's tree but
which is not present on Jean-Christophe's cleanup tree on which I based these
patches.
Moreover this patch doesn't use macros introduced by Nicolas' patch. I may
update it and it should go through Vinod's tree with a dependence on patch 1/3.
What's your point of view?
