Thank you for your bug report.
This should be fixed by this upstream commit, which landed in Linus' tree a couple of hours ago:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/platform/x86?id=8169bd3e6e193497cab781acddcff8fde5d0c416
Igor, if you do:
cat /sys/class/dmi/id/chassis_type
On your laptop, and the output is NOT "31" or "32" then this
fix should work for you.
If the output actually is "31" or "32 (which I do not expect),
then please let me know, because then we need a different fix.
I've also added this comment to the launchpad bug.
Regards,
Hans
