drm/i915: Move the irq wait queue initialisation into the ring init
Required so that we don't obliterate the queue if initialising the rings after the global IRQ handler is installed. [Jesse, you recently looked at refactoring the IRQ installation routines, does moving the initialisation of ring buffer data structures away from that routine make sense in your grand scheme?] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Reviewed-by: Ben Widawsky <ben@bwidawsk.net> Signed-off-by: Keith Packard <keithp@keithp.com>
