Please use a different lifetime name for this, 'bound should only be used f=
or
the bus device private data itself, as its lifetime defines this scope. May=
be
use 'drm instead?

The same is true for a couple of other places in this series, such as
Mmu<'bound>, VmAsData<'bound>, etc.

Please feel free to fix up on apply or in a follow-up patch.
