[Intel-gfx] [PATCH 07/17] drm/i915: Unify the appearance of gen3/4 irq_postistall hooks

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Do the irq_mask/enable_mask setup in the same way on gen3/4, and also
reorder the steps to make the code more uniform.
