snd/hda, drm/i915: Track the display_power_status using a cookie
drm/i915 is tracking all wakeref owners with a cookie in order to identify leaks. To that end, each rpm acquisition ops->get_power is assigned a cookie which should be passed to ops->put_power to signify its release (and removal from the list of wakeref owners). As snd/hda is already using a bool to track current status of display_power extending that to an unsigned long to hold the boolean cookie is a trivial extension, and will quell all doubt that snd/hda is the cause of the device runtime pm leaks. v2: Keep using the power abstraction for local wakeref tracking. v3: BUILD_BUG_ON impedance mismatch Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Takashi Iwai <tiwai@suse.de> Cc: Jani Nikula <jani.nikula@intel.com> Acked-by: Takashi Iwai <tiwai@suse.de> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190213152109.16997-1-chris@chris-wilson.co.uk
