Subject: [PATCH AUTOSEL 4.19 37/38] scsi: fcoe: Memory leak fix in fcoe_sysfs_fcf_del()
Date: Fri, 21 Aug 2020 12:18:06 -0400 [thread overview]
Message-ID: <20200821161807.348600-37-sashal@kernel.org> (raw)
In-Reply-To: <20200821161807.348600-1-sashal@kernel.org>
From: Javed Hasan <jhasan@marvell.com>
[ Upstream commit e95b4789ff4380733006836d28e554dc296b2298 ]
In fcoe_sysfs_fcf_del(), we first deleted the fcf from the list and then
freed it if ctlr_dev was not NULL. This was causing a memory leak.
Free the fcf even if ctlr_dev is NULL.
