Subject: media: v4l2-fwnode: Fix setting V4L2_MBUS_DATA_ACTIVE_HIGH/LOW flag Author: Ondrej Jirman megous@megous.com Date: Fri Dec 7 10:56:01 2018 -0500
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).
