From: Colin Ian King <colin.king@xxxxxxxxxxxxx> [ 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.
