-Subject: [PATCH 254/703] staging: bcm2835-camera: Handle empty EOS buffers
- whilst streaming
-
-The change to mapping V4L2 to MMAL buffers 1:1 didn't handle
-the condition we get with raw pixel buffers (eg YUV and RGB)
-direct from the camera's stills port. That sends the pixel buffer
-and then an empty buffer with the EOS flag set. The EOS buffer
-wasn't handled and returned an error up the stack.
-
-Handle the condition correctly by returning it to the component
-if streaming, or returning with an error if stopping streaming.
-
-Fixes: 9384167 "staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping"
