drm/i915: Really ignore long HPD pulses on eDP
Return IRQ_HANDLED from intel_dp_hpd_pulse() to properly ignore the long HPD pulse on eDP to avoid the never ending VDD off->HPD->VDD on->VDD off->HPD... cycle. This fixes a regression intoduced by commit b2c5c181ed18490648a02f8c7d562a3b9e8b96de Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jan 23 06:00:31 2015 +0100 drm/i915: Use symbolic irqreturn for ->hpd_pulse Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Jani Nikula <jani.nikula@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>
