This will be a growing patch-set of conversions and dead-code removal
towards the goal of retiring hci_request.c
The patch sets will be split amoung the work queues and delayed work
queues as initialized in hci_request_setup(), with the ultimate goal of
eliminating hci_request.c entirely.
Brian Gix (3):
Bluetooth: Remove dead code from hci_request.c
Bluetooth: Remove update_scan hci_request dependancy
Bluetooth: Convert delayed discov_off to hci_sync

2.36.1
This removes the remaining calls to HCI_OP_WRITE_SCAN_ENABLE from
hci_request call chains, and converts them to hci_sync calls.

The timed ending of Discoverability was handled in hci_requst.c, with
calls using the deprecated hci_req_add() mechanism. Converted to live
inside mgmt.c using the same delayed work queue, but with hci_sync
version of hci_update_discoverable().
