Subject: [PATCH 02/11] quota: Only module_put the format when existing
Date: Wed, 14 Aug 2019 14:18:25 +0200 [thread overview]
Message-ID: <20190814121834.13983-3-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20190814121834.13983-1-s.hauer@pengutronix.de>
For filesystems which do not have a quota_format_type such as upcoming
UBIFS quota fmt may be NULL. Only put the format when it's non NULL.
