From: Yue Haibing
Date: Sat Mar 15 2025 - 07:51:05 EST
In file included from <command-line>:
./drivers/gpu/drm/i915/display/intel_fbdev.h: In function ‘intel_fbdev_framebuffer’:
./drivers/gpu/drm/i915/display/intel_fbdev.h:32:16: error: ‘NULL’ undeclared (first use in this function)
32 | return NULL;
| ^~~~
./drivers/gpu/drm/i915/display/intel_fbdev.h:1:1: note: ‘NULL’ is defined in header ‘<stddef.h>’; did you forget to ‘#include <stddef.h>’?

./drivers/gpu/drm/i915/display/intel_fbdev.h:32:16: note: each undeclared identifier is reported only once for each function it appears in
32 | return NULL;
| ^~~~
Build fails if CONFIG_DRM_FBDEV_EMULATION is n, add missing header file.
Fixes: 9fa154f40eb6 ("drm/{i915,xe}: Run DRM default client setup")
