That means all the code in the DSI driver to specify and set loads before disabling a regulator is not actually doing anything useful. Let's remove it. It should be noted that all of the loads set that were being specified were pointless noise anyway. The only use for this number is to pick between low power and high power modes of regulators. Regulators appear to do this changeover at loads on the order of 10000 uA. You would a lot of clients of the same rail for that 100 uA number to count for anything. Note that now that we get rid of the setting of the load at disable time, we can just set the load once when we first get the regulator and then forget it. It should also be noted that the regulator functions regulator_bulk_enable() and regulator_set_load() already print error messages when they encounter problems so while moving things around we get rid of some extra error prints.
