[PATCH] sound, hda_eld: suspicious sizeof() in call tosnd_print_pcm_bits()

[Jesper Juhl]

In hdmi_show_short_audio_desc() we call snd_print_pcm_bits() like this:
  snd_print_pcm_bits(a->sample_bits, buf2 + 8, sizeof(buf2 - 8));
that last argument is supposed to be the size of the buffer that 
snd_print_pcm_bits() writes to, so I believe it should be this:
  snd_print_pcm_bits(a->sample_bits, buf2 + 8, sizeof(buf2) - 8);
