1/2 is a drive by fix.
2/2 uses devres resouce management helper devm_kzalloc() to auto-free
struct vchiq_drv_mgmt on error and .remove() paths.

It might be good to aware the devres issue and following talk might
give reviewers a helpful context:

- https://lpc.events/event/16/contributions/1227/
- https://archive.fosdem.org/2023/schedule/event/devm_kzalloc/

I am not totally sure if these problems, causes a blockers for these
patches. There are a couple of memory management issues I've spotted
which can be fixed? by devres (similar to this series) but probably I
will wait for initial feedback on this series.

Was supposed to mark this as RFC for discussion and yes, I have realised I've not written a commit message for 2/2.
