Subject: drm/msm/mdss: inline msm_mdss_icc_request_bw()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7323694e118a24ab954d3a16fe59a68b311cb462;p=linux.git

drm/msm/mdss: inline msm_mdss_icc_request_bw()

There are just two places where we set the bandwidth: in the resume and
in the suspend paths. Drop the wrapping function
msm_mdss_icc_request_bw() and call icc_set_bw() directly.
