Subject: regulator: core: Disable unused regulators after deferred probing is done
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fd482a3e3e20cddfb6d775ec0382f98a92b8a25e;p=linux-beck.git

regulator: core: Disable unused regulators after deferred probing is done

regulator_init_complete does a scan of regulators which dont have
always-on or consumers are automatically disabled as being unused.
However, with deferred probing, late_initcall() is too soon to
declare a regulator as unused as the regulator itself might not
have registered due to defferal - Example: A regulator deffered due
to i2bus not available which in turn is deffered due to pinctrl
availability.

Since deferred probing is done in late_initcall(), do the cleanup of
unused regulators by regulator_init_complete in late_initcall_sync
instead of late_initcall.
