Next one: i915 module reloading is broken because something is holding
onto a module reference and doesn't drop it. Didn't check which sets
of patches introduced this, but iirc this worked last week. Disabling
hda-intel gets in Kconfig gets rid of the problem, so I assume
something in the sound driver is leaking that reference ...

It's also causing lots and lots of red in our CI :( If we can't fix
this we need to disable snd-hda-intel there too.
