The commit [4b527b65 ALSA: hda - limit internal mic boost for Asus X202E] introduced the use of auto-parser code, but it forgot to add struct hda_gen_spec at the head of codec->spec which the auto-parser assumes silently. Without this record, it may result in memory corruption.

This patch adds the missing piece.

David, I queued this fix now. I'm going to send a pull request tomorrow or on Friday.
