The kbuild test robot reports the following build errors for
x86_64-randconfig-c1-0407:
All error/warnings:
net/built-in.o: In function `wiphy_new':
>> (.text+0x7684c): undefined reference to `rfkill_alloc'

These undefined sysbols are all satisfied if a "select RFKILL" is added to
Kconfig. This "fix" leads to another problem as follows:
>> nl80211.c:(.text+0x9032e): undefined reference to `rfkill_blocked'
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
To avoid substituting one build error for another, I added a "depends on
RFKILL".
My suspicion is that this particular error is caused by a kbuild bug, or that
the
selection of INPUT by ACPI_CMPC is wrong. In any case, that will be solved
separately.
