Subject: [PATCH] regmap: debugfs: emit a debug message when locking is disabled
Date: Wed, 13 Dec 2017 17:59:19 +0100	[thread overview]
Message-ID: <20171213165919.25058-1-brgl@bgdev.pl> (raw)

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.
