Subject: [PATCH 4/8] ubifs: do not ubifs_inode() on potentially NULL pointer
Date: Fri, 22 Jan 2021 16:15:32 +0100 [thread overview]
Message-ID: <20210122151536.7982-5-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210122151536.7982-1-s.hauer@pengutronix.de>
new_inode() may return NULL, so only derefence the return inode when
non NULL. This is merely a cleanup as calling ubifs_inode() on a NULL
pointer doesn't do any harm, only using the return value would.
