warn: struct type mismatch 'drm_framebuffer vs intel_framebuffer'
This implicit cast was correct as struct intel_framebuffer has struct
drm_framebuffer as its first member, but in case someone want to reorder
the fields for some reason, it's slightly safer to access the underlying
drm_framebuffer through intel_fb->base.
Also, having fewer static analysis warnings is a worthy goal.
