False positive IMHO. This is designed to be integrated into other
devices for boot display. vfio/display.c uses it that way. There
also is a standalone version (initially meant to be used for testing
only, but turned out to be useful on arm) in ramfb-standalone.c which
is a proper QOM object too.
take care,

I guess I should take the time to comment the false positives too in the code (Paolo made various other comments too). So next developer won't have to ask again.
