4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ondrej Jirman <megous@xxxxxxxxxx>
commit fa09d06522ceac428fdc5c2b57c572f6cfd0a8bb upstream.
When parallel bus is used and data-active is being parsed, incorrect
flags are cleared.
Clear the correct flag bits.
Fixes: e9be1b863e2c2948deb003df8edd9635b4611a8a (media: v4l: fwnode:
Use default parallel flags).
