Commit Message

Dheeraj Jamwal Oct. 21, 2014, 10:47 a.m. UTC 
From: Imre Deak <imre.deak@intel.com>

The power domains framework is internal to the i915 driver, so pass
drm_i915_private instead of drm_device to its functions.

Also remove a dangling intel_set_power_well() declaration.

No functional change.
