Subject: [PATCH] pinctrl: ocelot: fix duplicate debugfs entry
Date: Wed, 16 Feb 2022 13:27:27 +0100	[thread overview]
Message-ID: <> (raw)

This driver can have up to two regmaps. If the second one is registered
its debugfs entry will have the same name as the first one and the
following error will be printed:

[    2.242568] debugfs: Directory 'e2004064.pinctrl' with parent 'regmap' already present!

Give the second regmap a name to avoid this.

Fixes: 076d9e71bcf8 ("pinctrl: ocelot: convert pinctrl to regmap")
