Users load only module-bluetooth-discover, so the module argument has
to be added to that module. module-bluetooth-discover in turn loads
module-bluez5-discover, and the module argument needs to be added there
too. Finally, module-bluez5-discover loads module-bluez5-device, which
is the place where the option is actually used. The module argument
needs to be added to all three modules.

By the way, most technical mailing lists, including this one, prefer
the interleaved reply style:
