This bug definitely depends on kernel version. Both the fix mentioned
above in #8
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1597415/comments/8
and mainline kernel after this commit (found with reverse bisect), are
required. Marking as linux bug. Would be very nice if fix could make it
into Ubuntu 16.04 LTS.

e075b3c898e4055ec62a1f0ed7f3b8e62814bfb6 is the first bad commit

dell-wmi: Generate one sparse keymap for all machines
This patch reworks code for generating sparse keymap and processing WMI
events. It unifies procedure for generating sparse keymap and also unifies
big switch code for processing WMI events of different types. After this
patch dell-wmi driver does not differ between "old" and "new" hotkey type.
It constructs sparse keymap table with all WMI codes. It is because on some
laptops (e.g. Dell Latitude E6440) ACPI/firmware send both event types (old
and new).
Each WMI code in sparse keymap table is prefixed by 16bit event type, so it
does not change functionality on laptops with "old" hotkey support (those
without scancodes in DMI).
This allow us to distinguish between same WMI codes with different types in
sparse keymap. Thanks to this WMI events of type 0x0011 were moved from big
switch into sparse keymap table too.
This patch also fixes possible bug in parsing WMI event buffer introduced
in commit 5ea2559726b7 ("dell-wmi: Add support for new Dell systems"). That
commit changed buffer type from int* to u16* without fixing code. More at:
