[PATCH 0/2] Quirk to enable QCA9377 to discover BLE devices

[JoÃo Paulo Rechi Vita]

As reported previously on [1], it is currently not possible to discover
BLE devices with QCA9377 controllers. When trying to start an active
scanning procedure with this controller, three commands are queued,
LE_SET_RANDOM_ADDR, LE_SET_SCAN_PARAM and LE_SET_SCAN_ENABLE. After the
first command is sent to the controller, a command complete event for it
is received, and the second command is sent, an extra command complete
for the first command is received. At this point the kernel sends the
next command and fails to process the command complete event for the
LE_SET_SCAN_PARAM command, because when it arrives it does not match the
last command that was sent. This makes hdev->le_scan_type never be
updated and the kernel behaves as if a passive scanning procedure was
being performed, thus no device found events are sent to userspace.

[1] https://www.spinics.net/lists/linux-bluetooth/msg79102.html

I have received no replies on the previous report and on further
attempts to contact the QCA addresses that have submitted Bluetooth
firmware blobs to linux-firmware upstream. This series avoids the
problem described above, but I believe ideally the controller should not
be sending this extra command complete event.

I'm not 100% sure if the approach taken here is the best way to work
around this problem in the kernel, as I am not super familiar with the
HCI layer. I'll be happy to hear suggestions of better approaches.

Full logs from btmon can be found bellow this message, and the extra
command complete event can be seen at timestamp 27.420131.

Best regards,
