4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@xxxxxxx> commit f44cb4b19ed40b655c2d422c9021ab2c2625adb6 upstream. The Atheros 1525/QCA6174 BT doesn't seem working properly on the recent kernels, as it tries to load a wrong firmware ar3k/AthrBT_0x00000200.dfu and it fails. This seems to have been a problem for some time, and the known workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012.
