Sorry, I now see my question was interpretable as a request. Not my intention. I know the last thing LibreELEC developers need to do is continue to maintain 9.2 ... although you have tweaked it several times , hence .8, to the benefit of all end users and for that I thank you most sincerely.
LibreELEC 10 / Kodi 19.* Matrix seems to be a big step as it is. The RPi4 rev 1.4 is news to me but must be an added head scratching factor, I'm sure!
Occasionally peek at the commit feeds for the RPi firmware and LibreELEC, noticing the significant work happening consistently and in no way do I want to burden the devs with a 9.2.* branch request, adding to the workload.
Instead of a request, I was just seeking clarification as my compilation experience, and Linux driver knowledge, is minimal
Thanks for the link!
