From 6411ef218c12f6719597631d388f2b13945a5251 Mon Sep 17 00:00:00 2001

Subject: [PATCH 22/49] ALSA: hda - Fix power-map regression for HP dv6 & co
commit 6e1c39c6b00d9141a82c231ba7c5e5b1716974b2 upstream.
The recent fix for power-map controls (commit b0791dda813) caused
regressions on some other HP laptops. They have fixed pins but these
pins are exposed as jack-detectable. Thus the driver tries to control
the power-map dynamically per jack detection where it never gets on.
This patch adds the check of connection and it assumes the no jack
detection is available for fixed pins no matter what pin capability
says.
