Subject: [PATCH 03/11] fs: Make iput() accept NULL pointers
Date: Mon, 15 Jun 2020 08:02:21 +0200	[thread overview]
Message-ID: <20200615060229.7533-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20200615060229.7533-1-s.hauer@pengutronix.de>

Let iput() accept NULL pointers so that users do not have to test for
it.
