Arnd Bergmann 003d3e70db ALSA: ad1848: fix format string overflow warning ... The snd_pcm name is too long to fit into the card shortname or a part of the longname: sound/isa/ad1848/ad1848.c: In function 'snd_ad1848_probe': sound/isa/ad1848/ad1848.c:116:26: error: ' at 0x' directive writing 6 bytes into a region of size between 1 and 80 [-Werror=format-overflow=] sprintf(card->longname, "%s at 0x%lx, irq %d, dma %d", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sound/isa/ad1848/ad1848.c:116:2: note: 'sprintf' output between 22 and 128 bytes into a destination of size 80 sprintf(card->longname, "%s at 0x%lx, irq %d, dma %d", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ chip->pcm->name, chip->port, irq[n], dma1[n]); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This changes the code to use length-checking functions that truncate if necessary. The "[Thinkpad]" substring is now also part of the snprintf(), as that could also overflow the buffer.
