[PATCH 1/4] mfd/mc13783: remove obsolete private data

From: Uwe Kleine-KÃnig
Date: Wed Sep 29 2010 - 12:24:00 EST


The regulator driver was converted to get the needed data directly from
platform_data by

a10099b (regulator/mc13783: various cleanups)

so regulators and num_regulators can go away. Then apart from the flag
indicating that the adc does a conversion, flags is only a copy of the
flags member of platform_data. This flag isn't needed to be returned by
mc13783_get_flags, so mc13783_get_flags now gets the flags from
platform_data, too and the driver private member is renamed for clearity.
