Title:
Support rfkill-any led trigger for Fujitsu u727
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Xenial:
Fix Committed
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.
== Fix ==

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_codec_realtek to support the HW
without messing with the kernel packages.
I'm currently waiting for some reviews, like
https://www.spinics.net/lists/platform-driver-x86/msg14606.html
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.
