From 1fae788ed640e2a961c2edab54bfd56c73e2506a Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Tue, 23 May 2017 09:32:13 +0530 Subject: PM / OPP: Don't create debugfs "supply-0" directory unnecessarily We create "supply-0" debugfs directory even if the device doesn't do voltage scaling. That looks confusing, as if the regulator is found but we never managed to get voltage levels for it. Avoid creating such a directory unnecessarily.
