ALSA: hda - hdmi: Protect ELD buffer Because the eld buffer can be simultaneously accessed from both workqueue context (updating) and process context (kcontrol read), we need to protect it with a mutex to guarantee consistency. To avoid holding the mutex while reading the ELD info from the codec, we introduce a temporary eld buffer.
