With users both in i915 core and display, struct drm_device is the common denominator for the VLV IOSF SB users. Also use drm_device for the helpers on the display side to keep the static inlines as simple as possible. We can drop a number of dependencies on i915_drv.h with this. v2,v3: Rebase Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://lore.kernel.org/r/c1d013ed88ce2e3e5bdc15ce3bf01a3960b1e817.1747061743.git.jani.nikula@intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com>
