Subject: drm/i915: Pass intel_dbuf_bw to skl_*_calc_dbuf_bw() explicitly
X-Git-Tag: v6.16-rc1~144^2~20^2~30
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=18e6866615698f9dd714e47353022bd597a90a57;p=thirdparty%2Flinux.git

drm/i915: Pass intel_dbuf_bw to skl_*_calc_dbuf_bw() explicitly

Make skl_*_calc_dbuf_bw() a bit lower level passing in the
to be mutated dbuf_bw struct in explicitly. This will allow
more reuse later.
