Subject: [PATCH 3/7] ARM: omap: use cdev_open_by_name()
Date: Thu, 16 May 2024 09:08:18 +0200	[thread overview]
Message-ID: <20240516070822.2746845-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20240516070822.2746845-1-s.hauer@pengutronix.de>

cdev_by_name() returns a cdev without increasing its reference count. In
order to maintain a proper reference counting use cdev_open_by_name()
instead and make sure it's closed afterwards when no longer needed.
