Feature request - support kbd_backlight on Hewlett-Packard

[kedar kedar]

Hello,

Can anyone please try add support for controlling keyboard backlight
via sysfs on Hewlett-Packard notebooks?
Maybe in a similar way as this last year patch for Thinkpad?
https://lkml.org/lkml/2015/12/24/295
BTW: This functionality is already supported (minimaly) on Apple,
ASUS, Dell, Samsung, Sony, Thinkpad, Toshiba :-)

Thanks

I dunno if my corporate windows laptop has this feature, though I
can't do anything in near future regarding to this, no time.

In any case it looks like HP stuff is kinda orphaned in PDx86
subsystem (just occasional fixes happen).

Hi Kedar,

is there a bugzilla entry open for this? If not, this is a good way to
capture the problem and share details on the system with people that may
be able to help but do not have the hardware platform itself.
