Subject: [PATCH AUTOSEL 4.19 06/21] scsi: hpsa: Fix memory leak in hpsa_init_one()
Date: Mon,  9 Nov 2020 22:55:26 -0500	[thread overview]
Message-ID: <20201110035541.424648-6-sashal@kernel.org> (raw)
In-Reply-To: <20201110035541.424648-1-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.
