Hi Hans and Helen,

Is there trick to being able to run v4l2-ctl --stream-mmap on vimc

I am seeing

VIDIOC_STREAMON returned -1 (Broken pipe)

since 5.2 and narrowed it to the above commit.

I am working on vimc life-time problem and unable test my patches
because of this commit on 5.2

thanks,
-- Shuah
