[PATCH 08/16] drm/i915: Unify the appearance of gen3/4 irq_postistall hooks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

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.
