Add btusb sco driver support for AX210 TyP2
Browse files Browse the repository at this point in the history
This patch adds btusb sco driver support for Intel Bluetooth
AX210 (Typ2).

[Problem]
btusb sco drivers not probed for TyP2 cards, resulting in
not creating the btaudiosource sound card, which is required for BT HFP
sco call.

[Solution]
Add AX210 vendorid, productid info to the driver table. Now the sound
cards are listed with below cmd. As recommended from 6.0+ kernel,
the alsa sco driver should pass NULL for continous dma data and
snd_dma_continuous_data() is removed.

[Test]
Updated the driver ko file and checked the sound card listing.
