Subject: [PATCH v2 0/3] Bluetooth: Add btrealtek data struct and improve SCO sound quality of RTK chips

From: Hilda Wu <hildawu@...ltek.com>

Add btrealtek data struct and use definition of vendor flags to manage
the specific chip.
The Bluetooth: btusb: Workaround for spotty SCO quality patch is for
filter out duplicate packet for avoiding spotty SCO quality.
The Bluetooth: btsub: Ignore zero length of USB packets on ALT 6 patch
is for some Realtek chips need to transmit mSBC data continuously
without the zero length of USB packets.

Changes in v2:
 - Set the proper priv_size to hci_alloc_dev_priv().
 - Separate commits for functions.

Thank you for your review and suggestions.
