These vfuncs are defined on the "guc" struct so you can drop "_guc" from
their names. And maybe they shall be closer to existing "interrupts_enabled"
field to keep all related stuff together. Then we can try to do like this:
- bool interrupts_enabled;
+ struct {
+ bool enabled;
+ void (*reset)(struct drm_i915_private *dev_priv);
+ void (*enable)(struct drm_i915_private *dev_priv);
+ void (*disable)(struct drm_i915_private *dev_priv);
+ } interrupts;
