ALSA: hda - Fix regression of monitor_present flag in eld proc file
[ Upstream commit 023d8218ec0dfc30e11d4ec54f640e8f127d1fbe ] The commit [bd48128539ab: ALSA: hda - Fix forgotten HDMI monitor_present update] covered the missing update of monitor_present flag, but this caused a regression for devices without the i915 eld notifier. Since the old code supposed that pin_eld->monitor_present was updated by the caller side, the hdmi_present_sense_via_verbs() doesn't update the temporary eld->monitor_present but only pin_eld->monitor_present, which is now overridden in update_eld(). The fix is to update pin_eld->monitor_present as well before calling update_eld(). Note that this may still leave monitor_present flag in an inconsistent state when the driver repolls, but this is at least the old behavior. More proper fix will follow in the later patch.
