I also think this is the correct approach.

In the drivers/ tree, there are two mentions of MISC_DEVICES left:

finger@larrylap:~/wireless-testing-new> grep -r MISC_DEVICES drivers/*
drivers/misc/Kconfig:# This one has to live outside of the MISC_DEVICES conditional,
drivers/mmc/host/Kconfig:       select MISC_DEVICES
