Hi,
Quick self intro: I have take over drivers/platform/x86
maintainership from Andy; and I'm working my way through
the backlog of old patches in patchwork:

Thank you for your patch, I've applied this patch to my review-hans
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans
I've made one small change I've replaced the (ignored)
KEY_LIGHTS_TOGGLE key-code with KEY_KBDILLUMTOGGLE as that is
the correct code to use for toggling the kbd backlight on/off.
As the comment in input-event-codes.h says KEY_LIGHTS_TOGGLE
is for "/* Reading light on or off */".
Note this will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.
Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.
Regards,
Hans
