Sure, my aim here was to only solve the _build breakage_ by fixing the
Kconfig for this module (that used code from another kernel module
without listing it in its dependencies). If, as you say, the real
solution is that we should actually be taking out the offending call
to the other module itself, then please go ahead -- I don't know much
about the Bluetooth / HIDP subsytem anyway.
