Dear Maintainer,

I recently installed Debian testing on a new Dell Precision 7550. This
has 3 physical buttons under the trackpad. And I had the surprise that
only the left and middle ones were working (although at some point I
think I got evtest or a similar program to see something for the right
one, so it doesn't seem physically broken). Right clicks with an
external mouse work just fine.

In syslog, I see
Jan 18 13:19:01 hippo gnome-shell[1590]: libinput error: event14 - DELL09C3:00 0488:120A Touchpad: kernel bug: received BTN_RIGHT button event on a clickpad

A search with these strings led me to libinput merge request !516 (there
are more details in the earlier !481) which seems to be precisely about
my issue, and has a fix in master, although not in the 1.16 branch
because it requires a recent libevdev. Since Debian seems to have a
recent enough libevdev, I was wondering if you would be willing to
backport that patch? Unless you think that release 1.17 is just around
the corner.

(I did not try building libinput from the master branch yet)

now :-)

I should mention that this was fixed in testing a long time ago. I am not
closing the bug myself in case it motivates a backport for stable, but I
am not affected anymore and fine with the bug being closed.
