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.
