From: Fabio Estevam <[email protected]> Commit 9b947a13e7f6 ("regmap: use debugfs even when no device") allows the usage of regmap debugfs even when there is no device associated, which causes several warnings like this:
(NULL device *): Failed to create debugfs directory Do not print the warning in the case there is no associated device.
