This driver open-codes a few of the DPCD register reads when it can be simplified by using the helpers instead. This series reworks the MSM DP driver to use the DPCD helpers and removes some dead code along the way. There's the potential for even more code reduction around the test registers, but I haven't tried to do that yet.
