From a5ba91c380b8bcca21e6166fc71c5e5ac9f0db68 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Thu, 21 Dec 2017 12:12:50 +0100 Subject: [PATCH] regmap: debugfs: emit a debug message when locking is disabled We currently silently omit creating the debugfs entries when regmap locking is disabled. Users may not be aware of the reason for which regmap files don't show up in debugfs. Add a dev_dbg() message explaining that.
