4 Subject: [PATCH] media/v4l2_m2m: In buffered mode run jobs if either
5 port is streaming
6
7 In order to get the intended behaviour of the stateful video
8 decoder API where only the OUTPUT queue needs to be enabled and fed
9 buffers in order to get the SOURCE_CHANGED event that configures the
10 CAPTURE queue, we want the device to run should either queue be
11 streaming.
