PATCH 1/1 Bluetooth: btrtl: Enable WBS for the specific Realtek devices

From: Max Chou <[email protected]>

By this change, it will enable WBS supported on the specific Realtek BT devices, such as RTL8822C and RTL8852A.
In the future, it's able to maintain what the Realtek devices support WBS here.

There is a null-check on btrtl_dev->ic_info right above this switch
statement (https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=b649813eadbc062d8682f7a20aa025275707dd1f).
Is this still necessary with this change? (Sorry, I missed this during
our previous review).

Hi! Abhishek,
My bad! I should check the code base is the latest and follow it. I'll submit the v2 patch. Thanks for your review.

BRs,
Max
