From 9274c892430ef3240acf3f336916f64fe2b67b02 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 2 Jan 2017 14:41:00 +0530 Subject: [PATCH] PM / OPP: Rename and split _dev_pm_opp_remove_table() Later patches would want to remove OPP table (and its OPPs) using the opp_table pointer instead of 'dev'. In order to prepare for that, rename _dev_pm_opp_remove_table() as _dev_pm_opp_find_and_remove_table() split out part of it.
