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. Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl> Signed-off-by: Mark Brown <broonie@kernel.org>
