Which kernel tree should I use to apply your patch? tried with the mainline one
and got this error:
drivers/gpu/drm/i915/intel_display.c: In function ‘ironlake_compute_dpll’:
drivers/gpu/drm/i915/intel_display.c:8903:6: error: implicit declaration of
function ‘intel_crtc_has_type’ [-Werror=implicit-function-declaration]
intel_crtc_has_type(crtc_state, INTEL_OUTPUT_ANALOG))
