SRU Request submitted: https://lists.ubuntu.com/archives/kernel-team/2018-February/089892.html
** No longer affects: linux (Ubuntu Trusty) ** Description changed: + == 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 == + commit 9b8e34e211b15af429b72388a8f2b3b1823d172e + Author: Michał Kępień <ker...@kempniu.pl> + Date: Fri Jan 6 07:07:47 2017 +0100 + + 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. commit 9b8e34e211b15af429b72388a8f2b3b1823d172e Author: Michał Kępień <ker...@kempniu.pl> Date: Fri Jan 6 07:07:47 2017 +0100 - rfkill: Add rfkill-any LED 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.
