2013-09-15drm/radeon/dpm: rework auto performance level enableAlex Deucher
Calling force_performance_level() from set_power_state() doesn't work on some asics because the current power state pointer has not been properly updated at that point. Move the calls to force_performance_level() out of the asic specific set_power_state() functions and into the main power state sequence. Fixes dpm resume on SI.

2013-08-30drm/radeon: gcc fixes for sumo dpmAlex Deucher
Newer versions of gcc seem to wander off into the weeds when dealing with variable sizes arrays in structs. Rather than indexing the arrays, use pointer arithmetic.
