Arnd Bergmann d0dbf77130 IB/mlx4: fix sprintf format warning ... gcc-7 points out that a negative port_num value would overflow the string buffer: drivers/infiniband/hw/mlx4/sysfs.c: In function 'mlx4_ib_device_register_sysfs': drivers/infiniband/hw/mlx4/sysfs.c:251:16: error: 'sprintf' may write a terminating nul past the end of the destination [-Werror=format-overflow=] drivers/infiniband/hw/mlx4/sysfs.c:251:2: note: 'sprintf' output between 2 and 11 bytes into a destination of size 10 drivers/infiniband/hw/mlx4/sysfs.c:303:17: error: 'sprintf' may write a terminating nul past the end of the destination [-Werror=format-overflow=] drivers/infiniband/hw/mlx4/sysfs.c:303:3: note: 'sprintf' output between 2 and 11 bytes into a destination of size 10 While we should be able to assume that port_num is positive here, making the buffer one byte longer has no downsides and avoids the warning.
