Fix this by increasing the size of devname to accommodate 15 character netdev interface name and description. Remove length format precision for %s. We can fit entire name. Also increment the version. drivers/net/ethernet/cisco/enic/enic_main.c: In function ‘enic_open’: drivers/net/ethernet/cisco/enic/enic_main.c:1740:15: warning: ‘%u’ directive output may be truncated writing between 1 and 2 bytes into a region of size between 1 and 12 [-Wformat-truncation=] "%.11s-rx-%u", netdev->name, i); ^~ drivers/net/ethernet/cisco/enic/enic_main.c:1740:5: note: directive argument in the range [0, 16] "%.11s-rx-%u", netdev->name, i); ^~~~~~~~~~~~~ drivers/net/ethernet/cisco/enic/enic_main.c:1738:4: note: ‘snprintf’ output between 6 and 18 bytes into a destination of size 16 snprintf(enic->msix[intr].devname, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(enic->msix[intr].devname), ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "%.11s-rx-%u", netdev->name, i); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Govindarajulu Varadarajan Signed-off-by: David S.
