[PATCH v1 1/8] ALSA: hda: cs35l41: Use reset label to get GPIO for HP Zbook Fury 17 G9

From: Stefan Binding
Date: Thu Oct 26 2023 - 11:06:37 EST


This laptop has an incorrect setting in its _DSD for boost type, but
the rest of the _DSD is correct, and we can still use the reset label
to obtain the reset gpio.

Also fix channel map so that amp 0 is right, and amp 1 is left.

Fixes: 581523ee3652 ("ALSA: hda: cs35l41: Override the _DSD for HP Zbook Fury 17 G9 to correct boost type")
