ALSA: pcm: Fix superfluous snprintf() usage
show_pcm_class() returns obviously a short string that can't overflow PAGE_SIZE. And even if it were to overflow, using snprintf() there is just wrong, as it doesn't return the correct size. So simplify with sprintf() instead. Link: https://lore.kernel.org/r/20200313130223.8908-1-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
