Subject: [PATCH] Bluebooth: btusb: Fix quirk for Atheros 1525/QCA6174
Date: Thu, 15 Mar 2018 17:02:34 +0100 [thread overview]
Message-ID: <20180315160234.21789-1-tiwai@suse.de> (raw)
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.
The device in question is:
