Subject: drm/i915/rps: use intel_fsb_freq() and intel_mem_freq()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=6c9f41d8fa808f9020fbd64f74cf872080f2cd74;p=users%2Fhch%2Fmisc.git

drm/i915/rps: use intel_fsb_freq() and intel_mem_freq()

The rps init only happens once, so it's not important to use the cached
versions, and we can drop the dependency on them.
