    Subject[PATCH AUTOSEL for 4.14 06/97] Bluetooth: Add a new 04ca:3015 QCA_ROME device
    Date
    From: Ioan Moldovan <ioan.moldovan1999@gmail.com>

    [ Upstream commit 0a03f98b98c201191e3ba15a0e33f46d8660e1fd ]

    This patch adds the 04ca:3015 (from a QCA9377 board) Bluetooth device
    to the btusb blacklist and makes the kernel use the btqca module
    instead of btusb. The patch is necessary because, without it the
    04ca:3015 device defaults to using the btusb driver, which makes the
    WIFI side of the QCA9377 board unusable (obtains 0 MBps in speedtest,
    when the 04ca:3015 bluetooth is used with an audio headset).
