src/sys/netbt: bt_proto.c
Log Message:
netbt(4): Initialize bt_lock earlier.
Use a driver-class module modcmd init function, instead of a socket
domain init function; the socket-domain ones don't run until after
configure, but we need this to be initialized before configure so
that Bluetooth HCI drivers like ubt(4) can use it.
This is suboptimal but it's the least intrusive way I've thought of
to get this working, even if it's a little grody to make netbt a
`driver-class' (builtin) module. Note that this doesn't mean netbt
becomes dynamically loadable or unloadable; we're just using a module
for initialization ordering.
