From f74c0a29eca57e0024d31d41cbc4fc3d020bb42a Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Tue, 18 Jun 2019 12:45:20 -0400 Subject: [PATCH] media: coda: do not enforce 512-byte initial bitstream payload on CODA960 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.
