I was referring to hci_ll as to the line discipline driver, not the
line discipline itself.

The thing is, there are different Bluetooth combo chips which use HCI
to encapsulate commands to the sub-chips behind, and there's also the
implementation for TI chip doing that which is in the mainline. So
instead of keeping reinventing the wheel, I think it's fairly
beneficial for everything if we finally agree on something that works
for all the combo chips of the type.
