[PATCH AUTOSEL 4.9 04/12] scsi: hpsa: Fix memory leak in hpsa_init_one()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Keita Suzuki <keitasuzuki.park@xxxxxxxxxxxxxxxxxxxx>

[ 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.
