[Andy Green <andy@warmcat.com>]

drivers/net/qede/qede_main.c: In function ‘qed_slowpath_start’:
drivers/net/qede/qede_main.c:307:3: error:
‘strncpy’ output may be truncated copying 12 bytes from a string of length 127
[-Werror=stringop-truncation]
   strncpy((char *)drv_version.name, (const char *)params->name,
   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    MCP_DRV_VER_STR_SIZE - 4);
    ~~~~~~~~~~~~~~~~~~~~~~~~~
