I suppose you are talking about force-release quirk. That should be handled by systemd/udev now, not in kernel. The quirks you see in kernel are there for historical reasons, before we allowed userspace control force release mask. no it is for the atkbd_deactivate_fixup that resolves the problem for certain LG laptops. currently line 1792 of atkbd.c This is the relevant commit that lacks a match for my model: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/input/keyboard/atkbd.c?id=3d725caa9dcc78c3dc9e7ea0c04f626468edd9c9 | Adding this to atkbd.c quirks works well for me.

Should be fixed with: commit c01206796139e2b1feb7539bc72174fef1c6dc6e Author: Dmitry Torokhov <dmitry.torokhov@gmail.com> Date: Wed Sep 10 13:50:37 2014 -0700 Input: atkbd - do not try 'deactivate' keyboard on any LG laptops We are getting more and more reports about LG laptops not having functioning keyboard if we try to deactivate keyboard during probe. Given that having keyboard deactivated is merely "nice to have" instead of a hard requirement for probing, let's disable it on all LG boxes instead of trying to hunt down particular models. This change is prompted by patches trying to add "LG Electronics"/"ROCKY" and "LG Electronics"/"LW60-F27B" to the DMI list. https://bugzilla.kernel.org/show_bug.cgi?id=77051 Cc: stable@vger.kernel.org Reported-by: Jaime Velasco Juan <jsagarribay@gmail.com> Reported-by: Georgios Tsalikis <georgios@tsalikis.net> Tested-by: Jaime Velasco Juan <jsagarribay@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> |
LG notebooks have suffered from a bug making their keyboard non-functional. In this kernel version a fixup is applied. In the struct there are two LG laptops listed. Not mine.
