Arnd Bergmann 45e0b4b3d5 isdn: divert: fix sprintf buffer overflow warning ... One string we pass into the cs->info buffer might be too long, as pointed out by gcc: drivers/isdn/divert/isdn_divert.c: In function 'll_callback': drivers/isdn/divert/isdn_divert.c:488:22: error: '%d' directive writing between 1 and 3 bytes into a region of size between 1 and 69 [-Werror=format-overflow=] sprintf(cs->info, "%d 0x%lx %s %s %s %s 0x%x 0x%x %d %d %s\n", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/isdn/divert/isdn_divert.c:488:22: note: directive argument in the range [0, 255] drivers/isdn/divert/isdn_divert.c:488:4: note: 'sprintf' output 25 or more bytes (assuming 129) into a destination of size 90 This is unlikely to actually cause problems, so let's use snprintf as a simple workaround to shut up the warning and truncate the buffer instead.
