From: Sagar Arun Kamble <sagar.a.kamble@xxxxxxxxx> Prepared substructure rps for RPS related state. autoenable_work is used for RC6 too hence it is defined outside rps structure. As we do this lot many functions are refactored to use intel_rps *rps to access rps related members. Hence renamed intel_rps_client pointer variables to rps_client in various functions. v2: Rebase. v3: s/pm/gt_pm (Chris) Refactored access to rps structure by declaring struct intel_rps * in many functions.
