Re: [PATCH 4.19 15/39] ALSA: hda/generic: Add option to enforce preferred_dacs pairs

Hi!

From: Takashi Iwai tiwai@suse.de

commit 242d990c158d5b1dabd166516e21992baef5f26a upstream.

The generic parser accepts the preferred_dacs[] pairs as a hint for assigning a DAC to each pin, but this hint doesn't work always effectively. Currently it's merely a secondary choice after the trial with the path index failed. This made sometimes it difficult to assign DACs without mimicking the connection list and/or the badness table.

This patch adds a new flag, obey_preferred_dacs, that changes the behavior of the parser. As its name stands, the parser obeys the

Option added is never used as variable is never set. We don't need this in 4.19.
