If I try to compile I got CHK include/config/kernel.release make KBUILD_SRC= CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CHK include/generated/bounds.h CHK include/generated/timeconst.h CHK include/generated/asm-offsets.h CALL scripts/checksyscalls.sh CHK include/generated/compile.h CHK kernel/config_data.h CC drivers/gpu/drm/i915/i915_drv.o In file included from drivers/gpu/drm/i915/i915_drv.c:34:0: drivers/gpu/drm/i915/i915_drv.h:1706:23: error: field 'hotplug' has incomplete type struct i915_hotplug hotplug; ^ make[6]: *** [drivers/gpu/drm/i915/i915_drv.o] Error 1 So I commented this field out at the moment.
