[PATCH] regmap: debugfs: emit a debug message when locking is disabled

From: Bartosz Golaszewski
Date: Thu Dec 21 2017 - 06:12:50 EST


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.
