From 406e47652161d4f0d9bc4cd6237b36c51497ec75 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 27 Jan 2021 12:45:56 +0530 Subject: [PATCH] opp: Create _of_add_table_indexed() to reduce code duplication The implementation of dev_pm_opp_of_add_table() and dev_pm_opp_of_add_table_indexed() are almost identical. Create _of_add_table_indexed() to reduce code redundancy. Also remove the duplication of the doc style comments by referring to dev_pm_opp_of_add_table() from dev_pm_opp_of_add_table_indexed().
