From: Enric Balletbo i Serra <enric.balletbo@xxxxxxxxxxxxx> commit 022b02b4505ecea5eda02b18683531e49f7d8eb7 upstream. Add the power domains names to the power domain struct so we have meaningful name for every power domain. This also removes the following debugfs error message. [ 2.242068] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present! [ 2.249949] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present! [ 2.257784] debugfs: Directory 'power-domain' with parent 'pm_genpd' already present! ...
