Subject: PM / Domains: Remove pm_genpd_poweron() API
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ea823c7cbffa7bae311d78761866ac4db344c89b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PM / Domains: Remove pm_genpd_poweron() API

Once genpd could be configured to be built with CONFIG_PM_RUNTIME unset
(nowadays CONFIG_PM), the pm_genpd_poweron() API served a purpose, since
it allowed users to power on a PM domain.

As such configuration no longer is supported, users shall solely rely on
using some of the runtime PM APIs to power on a PM domain.
