From 735eb93ae267f0b5638045b86dbc1e0b7019e3e8 Mon Sep 17 00:00:00 2001 From: Alberto Panizzo Date: Mon, 14 Dec 2009 18:53:35 +0100 Subject: regulator: mc13783-regulator: correct the probing time. When the mc13783-regulator driver is built in kernel, probing it during the regulator subsystem initialisation result in a fault. That is because regulator subsystem is planned to be initialised very early in the boot process, before the mfd subsystem initialisation. The mc12783-regulator probing process need to access to the mc13783-core functionality to read/write mc13783 registers and so must be called after the mc13783-core driver initialisation. The way to do this is to let the kernel probe the mc13783-regulator driver when mc13783-core register his regulator subdevice.
