I think it just requires:
CONFIG_USB=m
CONFIG_RTLWIFI=y
> The fix is to select rtlwifi only when it is needed.
I don't think so. Consider this configuration:
CONFIG_PCI=y
CONFIG_USB=m
CONFIG_RTL_CARDS=y
CONFIG_RTL8192CE=y
CONFIG_RTL8192CU=m
CONFIG_RTLWIFI=y # maximum of RTL8192CE=y and RTL8192CU=m
The same breakage occurs.

This will break existing configurations as RTL_CARDS defaults to n.
Perhaps you should introduce separate modules for the common PCI and USB
support code, similarly to how the rt2x00 modules are organised.
