From 9e9704ea5baf09e4c61be5901439da34c39995d0 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Fri, 6 Oct 2017 09:02:06 +0200 Subject: [PATCH] PM / Domains: Rename genpd internals from pm_genpd_* to genpd_* Most of the functions names has already moved the genpd naming rules, however let's make this complete to avoid any further confusions.
