net: thunder_bgx: avoid format string overflow warning
gcc warns that the temporary buffer might be too small here: drivers/net/ethernet/cavium/thunder/thunder_bgx.c: In function 'bgx_probe': drivers/net/ethernet/cavium/thunder/thunder_bgx.c:1020:16: error: '%d' directive writing between 1 and 10 bytes into a region of size between 9 and 11 [-Werror=format-overflow=] sprintf(str, "BGX%d LMAC%d mode", bgx->bgx_id, lmacid); ^~~~~~~~~~~~~~~~~~~ drivers/net/ethernet/cavium/thunder/thunder_bgx.c:1020:16: note: directive argument in the range [0, 2147483647] drivers/net/ethernet/cavium/thunder/thunder_bgx.c:1020:3: note: 'sprintf' output between 16 and 27 bytes into a destination of size 20 This probably can't happen, but it can't hurt to make it long enough for the theoretical limit.
