[PATCH 4.20 118/145] media: v4l2-fwnode: Fix setting V4L2_MBUS_DATA_ACTIVE_HIGH/LOW flag

[Greg Kroah-Hartman]

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).
