[Patch v2 03/11] s5p-mfc: Use min scratch buffer size as provided by F/W

Smitha T Murthy
2017-03-03T09:07:01Z

After MFC v8.0, mfc f/w lets the driver know how much scratch buffer
size is required for decoder. If mfc f/w has the functionality,
E_MIN_SCRATCH_BUFFER_SIZE, driver can know how much scratch buffer size
is required for encoder too.
