If anyone has any objections, please let me know. ------------------ From: Takashi Iwai 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.
