That's not the goal of stable kernel releases/trees. If the driver
version that is in 4.19.y does not work for you on release 4.19.0, odds
of that "changing" in later stable releases is slim to none.
Especially without any specific bug reports or emails to the developers
to tell them what is broken and not working for you.
If however, you wish to stick with an out-of-tree driver, wonderful,
that's your choice. But don't claim that somehow the stable kernel
process is broken because of that, as it has nothing to do with this
type of thing.
Best of luck!
