I tend to agree here. I followed the pattern used with PCI support here,
but I also think that we don't need to be able to select all chips
individually. The following should be enough:

config RTW88_PCI
	tristate
	depends on PCI
	default y

config RTW88_USB
	tristate
	depends on USB
	default y

Still I'd like to continue with the current pattern to not block merging
of the USB support with this topic.

I could create a follow up patch though if that's desired.

Sascha
