No you don't. How does you driver know about what priority is correct
wrt all the other running RT tasks on the system?

Determining the right priority in a fixed priority scheduling system is
a system wide problem, nobody but the administrator can possibly even
begin to solve it.

There's a reason all RT irq threads are started at 50, its plain
impossible to do better.
