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 |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
