[Intel-gfx] [PATCH 3/4] drm/i915: Nuke drm_driver irq vfuncs
Ville Syrjala
ville.syrjala at linux.intel.com
Wed Jun 19 17:08:41 UTC 2019
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Stop using the irq vfuncs under drm_driver. That's not going to fly
in a mixed gen environment since the structure is shared between all
the devices.
