Re: [PATCH 02/22] drm/radeon/dpm: add new callbacks to get the current sclk/mclk

["Christian König" <deathsimple@vodafone.de>]

Might be a good idea to make that a bit more generic, e.g. add a 
get_current_clk callback and and a type (sclk, mclk, vclk, dclk, etc..) 
enum. But I can live with this approach as well.

Christian.
