   4 Subject: [PATCH 1271/1295] drivers: media: cfe: Increase default size of
   5  embedded buffer
   6
   7 Increase the size of the default embedded buffer to 16k. This is done to
   8 match what is advertised by the IMX219 driver and workaround a problem
   9 where the embedded stream is not actually used. Without full streams API
  10 support, the media pipeline validation will fail in these circumstances.
