3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
commit 7819d1c70eb6a57e43554d86e10b39d1e106ed65 upstream.
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.
