Subject: [PATCH 5/6] drm/msm/dp: Use function arguments for timing
configuration
From: Bjorn Andersson <quic_bjorande@...cinc.com>
dp_catalog_panel_timing_cfg() takes 4 arguments, which are passed from
the calling function through members of struct dp_catalog.
No state is maintained other than across this call, so switch to
function arguments to clean up the code.
