+Subject: [PATCH 408/454] staging: bcm2835-camera: Ensure timestamps never go
+ backwards.
+
+There is an awkward situation with H264 header bytes. Currently
+they are returned with a PTS of 0 because they aren't associated
+with a timestamped frame to encode. These are handled by either
+returning the timestamp of the last buffer to have been received,
+or in the case of the first buffer the timestamp taken at
+start_streaming.
+This results in a race where the current frame may have started
+before we take the start time, which results in the first encoded
+frame having an earlier timestamp than the header bytes.
+
+Ensure that we never return a negative delta to the user by checking
+against the previous timestamp.
