ALSA: als100: fix format string overflow warning
The compiler sees that the format string might overflow for the longname:
sound/isa/als100.c: In function 'snd_als100_pnp_detect':
sound/isa/als100.c:225:27: error: ', dma ' directive writing 6 bytes into a region of size between 0 and 64 [-Werror=format-overflow=]
sprintf(card->longname, "%s, %s at 0x%lx, irq %d, dma %d",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
sound/isa/als100.c:225:3: note: 'sprintf' output between 24 and 113 bytes into a destination of size 80
sprintf(card->longname, "%s, %s at 0x%lx, irq %d, dma %d",
Open-coding "shortname" here gets us below the limit, and using
snprintf() is a good idea too.
