The commit was applied to make further commits apply cleanly, but the commit depends on other commits in the same patchset. I.e. the controlling DSI host would need a change too. Thus one would need to backport the full patchset changing the DSI hosts and all downstream DSI device drivers. Revert the commit and fix up the conflicts with the backported fixes to the lt8912b driver.
