Compilation error due to header not found

[Pratik Singhal]

Hello all, I have used the file "dev/sound/pcm/sound.h" in a kernel driver
made for ac97 codec for Allwinner A10. This file further includes the file
"dev/sound/pcm/channel.h" which further includes the file "channel_if.h".

I have checked in  ~HEAD and the file channel_if.h doesn't exist in that
particular directory and as a result, I am getting a compilation error when
I compile the kernel complaining about the missing file "channel_if.h" .

How can I resolve this error ?
