From 120f80518125b8c312007a54106759d608487553 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 2 Jan 2013 15:32:00 +0000 Subject: [PATCH] regmap: debugfs: Fix attempts to read nonexistant register blocks Return the start of the last block we tried to read rather than a position, and also make sure we update the byte position while we're at it. Without this reads that go into nonexistant areas get confused.
