Kai Vehmanen dbdc1c1296 ALSA: hda/hdmi - add retry logic to parse_intel_hdmi() 
[ Upstream commit 2928fa0a97 ]

The initial snd_hda_get_sub_node() can fail on certain
devices (e.g. some Chromebook models using Intel GLK).
The failure rate is very low, but as this is is part of
the probe process, end-user impact is high.

In observed cases, related hardware status registers have
expected values, but the node query still fails. Retrying
the node query does seem to help, so fix the problem by
adding retry logic to the query. This does not impact
non-Intel platforms.
