Remove test of command reply status as it is already performed by
__hci_cmd_sync().
__hci_cmd_sync_ev() function already returns an error if it got a
non-zero status either through a Command Complete or a Command
Status event.
For both of these events the status is collected up in the event
handlers called by hci_event_packet() and then passed as the second
parameter to req_complete_skb(). The req_complete_skb() callback in
turn is hci_req_sync_complete() for __hci_cmd_sync_ev() which stores
the status in hdev->req_result. The hdev->req_result is then further
converted through bt_to_errno() back in __hci_cmd_sync_ev().

Realtek ship a variety of bluetooth USB devices that identify
themselves with standard USB Bluetooth device class values, but
require a special driver to actually work. Without that driver,
you never get any scan results.
More recently however, Realtek appear to have wisened up and simply
posted a firmware update that makes these devices comply with
normal btusb protocols. The firmware needs to be uploaded on each boot.
Based on Realtek code from https://github.com/lwfinger/rtl8723au_bt
('new' branch).
This enables bluetooth support in the Gigabyte Brix GB-BXBT-2807 which
has this RTL8723BE USB device:

There is no change to the USB descriptor after firmware update,
however the version read by HCI_OP_READ_LOCAL_VERSION changes from
0x8723 to 0x3083.
This has also been tested on RTL8723AE and RTL8821AE. Support for
RTL8761A has also been added, but that is untested.

The driver callbacks in the Atheros support were all in a random order
and did not help readability of this driver. So reorder them to make
them aligned with what other Bluetooth UART drivers do. This patch is
not changing any actual code.

The majority of Intel Bluetooth vendor commands are shared between USB

will hold all Intel specific commands, but for now just start with the
commands to change the Bluetooth public address and check for the

Future H:4 based UART drivers require custom packet types and custom
receive functions. To support this, extended the h4_recv_buf function
with a packet definition table.
For the default H:4 packets types of ACL data, SCO data and events,
provide helpers to reduce the amount of code duplication.
