3.16.63-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.k...@canonical.com>
commit f7db2beb4c2c6cc8111f5ab90fc7363ca91107b6 upstream.
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")
