From 23b5cc2ab6783256cf06779e1d522482b819b808 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 29 Apr 2010 10:55:09 +0300 Subject: [PATCH] regulator: prevent registration of matching regulator consumer supplies Acked-by: Mark Brown Pointer comparison is not sufficient for non-NULL device name matching, so use strcmp().
