[v2,03/10] media: vicodec: add field 'buf' to fwht_raw_frame

Commit Message

Dafna Hirschfeld Feb. 15, 2019, 1:05 p.m. UTC

Add the field 'buf' to fwht_raw_frame to indicate
the start of the raw frame buffer.
This field will be used to copy the capture buffer
to the reference buffer in the next patch.
