[PATCH v4 0/2] drm/i915: IRQ fixes

[Thomas Zimmermann]

Fix a bug in the usage of IRQs and cleanup references to the DRM
IRQ midlayer.

Preferably this patchset would be merged through drm-misc-next.

v4:
	* switch IRQ code to intel_synchronize_irq() (Daniel)
v3:
	* also use intel_synchronize_hardirq() from other callsite
v2:
	* split patch
	* also fix comment
	* add intel_synchronize_hardirq() (Ville)
	* update Fixes tag (Daniel)

[PATCH v4 1/2] drm/i915: Use the correct IRQ during resume

[Thomas Zimmermann]

The code in xcs_resume() probably didn't work as intended. It uses
struct drm_device.irq, which is allocated to 0, but never initialized
by i915 to the device's interrupt number.

Change all calls to synchronize_hardirq() to intel_synchronize_irq(),
which uses the correct interrupt. _hardirq() functions are not needed
in this context.

v4:
	* switch everything to intel_synchronize_irq() (Daniel)
v3:
	* also use intel_synchronize_hardirq() at another callsite
v2:
	* wrap irq code in intel_synchronize_hardirq() (Ville)
