      ALSA: hda_intel: more strict alc880_parse_auto_config dig_nid checking · 9d30937a
      Jaroslav Kysela authored
      On some IbexPeak systems with ALC889A errors like "azx_get_response
      timeout, switching to polling mode: last cmd=0xaf9f000b" are produced,
      because non-existent codec #10 is wrongly accessed.
      
      The problem is that snd_hda_get_connections() returns out-of-range result
      for NID 0x1c (something like 0xf8f9 or 0xffff).
      
      This patch adds a check to alc880_parse_auto_config() to avoid using
      of this out-of-range NIDs. A better fix maybe to improve
      snd_hda_get_connections() routine to check for valid NID ranges if
      NIDs are expected as result.
