[PATCH] staging: most: dim2: read done_buffers count locally from HDM channel

[Deepak R Varma]

The done_buffer count can be directly read from HDM channel instead of
calling the dim_get_channel_state function. This change also results in
obsoleting the dim_channel_state local structure variable.

PLEASE NOTE: I have only built the module on my machine, but have not tested it.
I am not sure how to test this change. I am willing to test it with appropriate
guidance provided I have the necessary hardware.
