Hi,
thanks for taking an interest in these drivers.
I original submitted this code because I though I needed it for my
mt7621 hardware, but I've subsequently realized that neither of these
dma drivers are used in this hardware.
Consequently I cannot test any changes you make.
But maybe you can - which would be excellent!
So this is just letting you and Greg know that despite my stated
interest, I cannot actually review or test this.
Thanks,
NeilBrown
