Subject: [PATCH AUTOSEL 4.9 04/12] scsi: hpsa: Fix memory leak in hpsa_init_one()
Date: Mon, 9 Nov 2020 22:56:25 -0500 [thread overview]
Message-ID: <20201110035633.425030-4-sashal@kernel.org> (raw)
In-Reply-To: <20201110035633.425030-1-sashal@kernel.org>
From: Keita Suzuki <keitasuzuki.park@sslab.ics.keio.ac.jp>
[ Upstream commit af61bc1e33d2c0ec22612b46050f5b58ac56a962 ]
When hpsa_scsi_add_host() fails, h->lastlogicals is leaked since it is
missing a free() in the error handler.
Fix this by adding free() when hpsa_scsi_add_host() fails.
