Linux 5.2 - vimc streaming fails with format error

[shuah]

Hi Hans and Helen,

vimc streaming fails on Linux 5.2-rc1

vimc: format doesn't match in link Scaler->RGB/YUV Capture

You can reproduce this easily with v4l2-ctl

Streaming works fine on Linux 5.1

I narrowed it to the following commit.
commit b6c61a6c37317efd7327199bfe24770af3d7e799

    media: vimc: propagate pixel format in the stream


Please take a look.

thanks,
