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

[Bartosz Golaszewski]

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.
