snd_ac97_get_name() blindly assumes that the name buffer is large enough, but we should be more careful. Pass the max buffer length and allow trimming to the size. Only a cosmetic safety matter, no functional changes intended. Signed-off-by: Takashi Iwai <tiwai@suse.de> Link: https://patch.msgid.link/20250710100727.22653-101-tiwai@suse.de
