The samsung-laptop.ko module is enabling the use of the keyboard backlight keys.

This bugzilla is about display and graphics, not about keyboard. Try these people and lists instead (or bugzilla.kernel.org, but there's a risk nobody notices:

$ get_maintainer.pl -f ./drivers/platform/x86/samsung-laptop.c Corentin Chary corentin.chary@gmail.com (maintainer:SAMSUNG LAPTOP DRIVER) Darren Hart dvhart@infradead.org (maintainer:X86 PLATFORM DRIVERS) Andy Shevchenko andy@infradead.org (maintainer:X86 PLATFORM DRIVERS) platform-driver-x86@vger.kernel.org (open list:SAMSUNG LAPTOP DRIVER) linux-kernel@vger.kernel.org (open list)

The BIOS is put into CSM mode.

For i915 we don't really support the CSM mode. Please use UEFI instead.
