Apologies if this has already been reported and fixed, I have not seen
anything on lore.kernel.org or drm-intel about it.
This patch as commit e74c6aa955ca ("drm/i915/fbc: Register per-crtc
debugfs files") breaks the build when CONFIG_DEBUG_FS is disabled.
drivers/gpu/drm/i915/display/intel_fbc.c: In function ‘intel_fbc_crtc_debugfs_add’:
drivers/gpu/drm/i915/display/intel_fbc.c:1817:61: error: ‘struct drm_crtc’ has no member named ‘debugfs_entry’
1817 | intel_fbc_debugfs_add(plane->fbc, crtc->base.debugfs_entry);
