ALSA: x86: Fix driver name string overflow
The driver sets card->driver name string over its size (16 bytes). Shorten the name string to fit with it. Also, set more verbose string to card->shortname and ->longname. This doesn't have to be identical with card->driver at all. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
