Hi Matthew,
I am requesting the experts in the filesystem subsystem to come to a
consensus here.
This is not my area of expertise at all but every time I have addressed

- remove bitfields
- remove Kconfig default m
- adjust formatting and some naming based on feedback
- fix error handling conditions
- use appropriate return codes
- use memcpy_toio instead of direct access to PCIE bar
