Bug Description
== SRU Justification ==
This bug was reported against a Fujitsu u7x7 laptop series based on Skylake hardware.
It has a single rfkill button and a single LED for wlan and bluetooth. Both
drivers currently provide a single rfkill trigger, so the led could
just be assigned to one. This was resolved by mainline commit 9b8e34e211, which added a
"rfkill-any" led trigger to correctly handle the led with multiple
rfkill devices. That was added by one of the fujitsu-laptop maintainers and
the driver sets it as the default trigger.
Commit 9b8e34e211b1 is in mainline as of 4.11-rc1.

rfkill: Add rfkill-any LED trigger
== Regression Potential ==
Medium. This commit affects all arches, but it has been in mainline since
4.11-rc1 with no reported issues.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
== Original Bug Description ==
I got new HW from our supplier, which is the Fujitsu u7x7 laptop series based on Skylake hardware.
It has a single rfkill button and a single LED for wlan and bluetooth. Both device driver currently provide a single rfkill trigger, so the led could just be assigned to one. As a result the upstream kernel got a new "rfkill-any" led trigger to correctly handle the led with multiple rfkill devices. That was added by one of the fujitsu-laptop maintainers and the driver sets it as the default trigger.

rfkill: Add rfkill-any LED trigger
Normally I would simply patch the affected modules using DKMS, like the i915_bpo driver, fujitsu-laptop and snd_hda_
I'm currently waiting for some reviews, like https:/
But the rfkill support is compiled in, so I can't patch it using DKMS.
So my first proposed fix would be to include a backport of this patch. Alternatively rfkill can be compiled as a module, so I can patch it and provide an updated module.

I built a test kernel with commit 9b8e34e211b15af 429b72388a8f2b3 b1823d172e. The test kernel can be downloaded from: kernel. ubuntu. com/~jsalisbury /lp1745130

Can you test this kernel and see if it resolves this bug?
Note, to test this kernel, you need to install both the linux-image and linux-image-extra .deb packages.
Thanks in advance.
