[PATCH for-5.0 2/4] hw/usb: Remove the USB bluetooth dongle device |
|
Date: |
Wed, 20 Nov 2019 10:10:12 +0100 |
We are going to remove the bluetooth backend, so the USB bluetooth
dongle can not work anymore. It's a completely optional device, no
board depends on it, so let's simply remove it now.

-the @option{-bt hci} option, @pxref{bt-hcis,,allowed HCI types}. If
-no type is given, the HCI logic corresponds to @code{-bt hci,vlan=0}.
-This USB device implements the USB Transport Layer of HCI. Example
