Subject: ALSA: hda - Add missing hda_gen_spec to struct via_spec
From: Takashi Iwai <[email protected]>
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.
