From d0087e72710ca7d1b309bf427286da58418ea89e Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Fri, 30 Aug 2019 09:17:37 +0200 Subject: regulator: provide regulator_bulk_set_supply_names() There are many regulator consumers who - before using the regulator bulk functions - set the supply names in regulator_bulk_data using a for loop. Let's provide a simple helper in the consumer API that allows users to do the same with a single function call.
