As of commit 5451781dadf8 ("regulator: core: Only count load for
enabled consumers"), a load isn't counted for a disabled
regulator. 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 need 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.
