[Intel-gfx] [PATCH 3/3] [v2] i915: fix backlight configuration issue

2021-10-27 Thread Arnd Bergmann
From: Arnd Bergmann The i915 driver can use the backlight subsystem as an option, and usually selects it when CONFIG_ACPI is set. However it is possible to configure a kernel with modular backlight classdev support and a built-in i915 driver, which leads to a linker error: drivers/gpu/drm/i915/d
