Subject: [PATCH AUTOSEL 3.18 10/12] vxge: ensure data0 is initialized in when fetching firmware version information
Date: Wed, 26 Dec 2018 17:57:38 -0500 [thread overview]
Message-ID: <20181226225741.151608-10-sashal@kernel.org> (raw)
In-Reply-To: <20181226225741.151608-1-sashal@kernel.org>
From: Colin Ian King <colin.king@canonical.com>
[ Upstream commit f7db2beb4c2c6cc8111f5ab90fc7363ca91107b6 ]
Currently variable data0 is not being initialized so a garbage value is
being passed to vxge_hw_vpath_fw_api and this value is being written to
the rts_access_steer_data0 register. There are other occurrances where
data0 is being initialized to zero (e.g. in function
vxge_hw_upgrade_read_version) so I think it makes sense to ensure data0
is initialized likewise to 0.
Detected by CoverityScan, CID#140696 ("Uninitialized scalar variable")
Fixes: 8424e00dfd52 ("vxge: serialize access to steering control register")
