That's good, but in the end, we want to get rid of BYTE, WORD, and DWORD
usages in this driver, can you just start replacing them with the proper
types?

Hi

The naming is misleading, they are not pointers.

I have a upcoming patch to remove them.

A pointer does not fit in u32 on all arches, only unsigned long works
