As mentioned in my previous mail, please consider adding support for
version 0 instead, which would fix this issue in a better way.

If that's not possible, then sure, this patch is fine.  But ideally this
warning should tend to lead to a patch to the bgrt driver adding support
for the new version (or in this case the old version), rather than just
silencing the warning.
