[Raphaël Jakse <raphael.jakse@xxxxxxxxx>]

The patch in my opinion is a regression for some specific laptops like 
mine. We go from "everything works except Bluetooth" to "The system 
works badly, and Bluetooth still doesn't work".

Someone who doesn't know the bug can't even guess easily this is caused 
by the Bluetooth driver (if (s)he even know what is a driver, and 
messing with kernel modules and/or bios is not an option for most people).

I will install the new kernel and report a new bug. I think the new 
report should get a "critical" level. This update will break existing 
installations, which should never happen.

Status in linux package in Ubuntu:
  Fix Released
Status in linux-firmware package in Ubuntu:
  Confirmed
Status in linux source package in Vivid:
  Fix Committed
Status in linux-firmware source package in Vivid:

Bug description:
  This is (kind of) a duplicate of:

  (please read)

  I can't use Bluetooth with my AR9462 WLAN/BT-Combo.
  In the link above, it has been fixed, but not for my Adapter ID/Firmware:

  System:
  Ubuntu 14.10 utopic 64bit - 3.16.0-24-generic x86_64

  lspci -nnk
  02:00.0 Network controller [0280]: Qualcomm Atheros AR9462
  Wireless Network Adapter [168c:0034] (rev 01)
   Subsystem: Lite-On Communications Inc Device [11ad:0802]
   Kernel driver in use: ath9k

  lsusb (identified Bluetooth Device)
  Bus 002 Device 003: ID 04ca:300d Lite-On Technology Corp.

  ath9k.conf
  options ath9k btcoex_enable=1

  The "04ca:300d" ID is not in the Kernel, so i added it via dkms.

  I took ath3k.c and btusb.c out of the 3.16.0-24-generic source files
  and changed them:

  sudo dkms build -m ar9462 -v 1.5.1

  (DKMS package in the same style/versioning as in the bug report above)

  dkms status

  Now the new output:

  My patch works, but just like in the bug report above, a Firmware file is missing:
  AthrBT_0x11020100.dfu

  I found it neither in linux-firmware (http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/ar3k)
  nor elsewhere.
