From: Libin Yang <libin.yang at linux.intel.com>

commit d10a80de04a3a8c0d7c1567cbc0a8d2e1181c10a upstream.

hdmi_find_pcm_slot return -EBUSY when not no pcm slot found,
not -ENODEV. So the caller should compare with -EBUSY.

Fixes: a76056f2e57e ('ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug')
