Subject: media: coda: do not enforce 512-byte initial bitstream payload on CODA960 Author: Philipp Zabel <[email protected]> Date: Tue Jun 18 12:45:20 2019 -0400 On CODA960, sequence initialization can succeed if less than 512 bytes are ready in the bitstream ring buffer. On other variants, warn about too small payload in start_streaming.
