** Description changed:
+ [SRU Justification]
+
+ [Impact]
+ When using a bluetooth headset the ad2p profile is supported but the
+ hsp/hfp profile doesn't work.
+
+ [Fix]
+ Using the latest firmware with patch version 42 solves from commit
+ 629a5e089e30 ("linux-firmware: Update firmware patch for Intel
+ Bluetooth 7260 (B5/B6)").
+
+ [Test Case]
+ Pair with headset/mobile phone with HSP/HFP support and try A/V
+ control.
+
+ [Regression Potential]
+ Low. This upgrades only the firmware blob used by affected hardware,
+ and the proposed blob is also used by later releases.

--problem :
The bluetooth part of the intel 7260 wifi/bluetooth card needs a firmware
file to operate.
The version of my card is reported in dmesg as :
Bluetooth: hci0: read Intel version: 3707100180012d0d00
this will load firmware file
Bluetooth: hci0: Intel Bluetooth firmware file: intel/ibt-
hw-37.7.10-fw-1.80.1.2d.d.bseq
When using a bluetooth headset the ad2p profile is supported but the
hsp/hfp profile doesn't work, I believe the version in the current
linux-firmawre package is patch version 39.
--solution :
- Using the latest firmware with patch version 42 solves the problem :

With this firmware the hsp/hfp profile is working, this means the
microphone and the sound of the bluetooth headset are working correctly.
