[alsa-devel] [PATCH] ASoC: factor out intel_scu_ipc related read/write

[Lu Guanqun]

Hi Mark,

How do you think of this approach?

Hi Vinod,

I don't have the mfld hardware, so it's a not tested patch. I want your
ack or dis-ack on this. :)

Another way to do this to simply override codec->read and codec->write
with the intel_scu_read/write stuff.  But then I realize we may later
take advantage of soc cache, therefore it's not appropriate to simply
override these two operations.
