[PATCH V2 1/9] mfd: 88pm800: fix NULL pointer error
From: Chao Xie
Date: Fri Jun 14 2013 - 01:24:12 EST
From: Yi Zhang <yizhang@xxxxxxxxxxx>
move "device_800_init" to fix NULL pointer error when
calling "device_gpadc_init"
for "device_gpadc_init" needs "subchip->regmap_gpadc"
to set registers via regmap interface
