From 3b58ee13da7510115b66f71c67c9e87b47e9c4aa Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Fri, 13 Dec 2013 09:14:07 -0800 Subject: regmap: Allow regmap_bulk_read() to work for "no-bus" regmaps regmap_bulk_read() should decay to performing individual reads if we're using a "no-bus" regmap. Unfortunately, it returns an error because there is no map->bus pointer. Fix it.
