Actually, RTL8192CE does not depend on USB nor does the implementation prior to
these patches.

I do see a couple of problems with the Kconfig. RTL8192CE needs to have a
dependence on PCI, and RTLWIFI needs to be dependent on RTL8192CE || RTL8192CU.

Sure it would be possible to split rtlwifi into 3 parts. I don't know how much
work it would be, but the lsmod size for all 3 parts together is 113332. If we
take the USB part out, it is 101654. Is this enough of a memory savings once the
additional memory to handle the linkage between the core and the PCI/USB parts
is taken into account?

Thanks,
