mfd: 88pm800: Fix NULL pointer dereference
Move "device_800_init" to fix NULL pointer error when calling "device_gpadc_init" as it needs "subchip->regmap_gpadc" to set registers via regmap interface Signed-off-by: Yi Zhang <yizhang@marvell.com> Signed-off-by: Chao Xie <chao.xie@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
