			Surprisingly many places depend on debugfs.h to be included via drm_print.h. Fix them. v3: Also fix armada, ite-it6505, imagination, msm, sti, vc4, and xe v2: Also fix ivpu and vmwgfx Reviewed-by: Andrzej Hajda <andrzej.hajda@intel.com> Acked-by: Maxime Ripard <mripard@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240410141434.157908-1-jani.nikula@intel.com Acked-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> # drm/msm Acked-by: Matt Coster <matt.coster@imgtec.com> # drm/imagination Acked-by: Alex Deucher <alexander.deucher@amd.com> Acked-by: Lucas De Marchi <lucas.demarchi@intel.com> Acked-by: Robert Foss <rfoss@kernel.org> #drm/bridge Reviewed-by: Lyude Paul <lyude@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240422121011.4133236-1-jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
