[Intel-gfx] [PATCH v3 06/27] drm/i915: Track IRQ state in local device state

Thomas Zimmermann
2021-06-24T07:29:56Z

Replace usage of struct drm_device.irq_enabled with the driver's
own state field struct drm_i915_private.irq_enabled. The field in
the DRM device structure is considered legacy and should not be
used by KMS drivers.
