* Removed unnecessary MOD_INC/DEC_USE_COUNT in host adapter drivers
  (i2c-via bit-lp bit-velle)

You can now rmmod adapters even when they have registered clients.
Without this, you would have to detach the clients first. Only way of doing
this is to rmmod the client drivers, but the same drivers might be used to
access clients behind other hosts.
