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.
