4.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@xxxxxxx>
commit c64c1437afb14ebc900e40910f31ffb20bf652ad upstream.
i915 get_eld ops may return an error when no encoder is connected, and
currently we regard the error as fatal and skip the whole ELD
handling. This ended up with the missing ELD update at unplugging.
This patch fixes the issue by treating the error as the unplugged
state, instead of skipping the rest.
