[PATCH v3 0/4] drm/i915/display: DMC wakelock implementation

[Luca Coelho <luciano.coelho@intel.com>]

Hi,

This is the fifth version of my series, the third as a proper
patchset.

These are the changes:

In v3:
   * Fixed some checkpatch issues.

In v2:
  * Enable/disable the wakelocks on DC5-6 entry and exit instead of on
    DMC load and unload;
  * Added bspec link to the commit message;
  * A bunch of other small changes;
  * For the complete list of changes and discussions, please look at
    the patchset in patchwork:
    https://patchwork.freedesktop.org/series/128628/

Please review.

Cheers,
Luca.
