Kconfig circular dependency question

A kernel build is reporting the following:

net/rfkill/Kconfig:4:error: recursive dependency detected!
net/rfkill/Kconfig:4: symbol RFKILL is selected by R8723AU
drivers/staging/rtl8723au/Kconfig:1: symbol R8723AU depends on USB
drivers/usb/Kconfig:41: symbol USB is selected by MOUSE_APPLETOUCH
drivers/input/mouse/Kconfig:162: symbol MOUSE_APPLETOUCH depends on INPUT
drivers/input/Kconfig:8: symbol INPUT is selected by ACPI_CMPC
drivers/platform/x86/Kconfig:635: symbol ACPI_CMPC depends on RFKILL

What is the recommended way to avoid this circularity? Of course, R8723AU could select USB rather than depending on it, but that does not seem quite right.
