Bluetooth: Add a new 04ca:3015 QCA_ROME device

Ioan Moldovan · holtmann · commit 0a03f98b98c2 · 2017-12-26T21:53:41.000+01:00
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).
