drm/i915: Handle HPD when it has actually occurred
Writing to PCH_PORT_HOTPLUG for each interrupt is not required. Handle it only if hpd has actually occurred like we handle other interrupts. v2: Make few variables local to if block (Ville) v3: Add check for ibx/cpt both (Ville). While at it, remove the redundant check for hotplug_trigger from pch_get_hpd_pins v4: Indentation (Ville) Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Sonika Jindal <sonika.jindal@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
