[PATCH 2/2] ASoC: rt5677: make ACPI property names match _DSD

From: Fletcher Woodruff
Date: Mon Apr 01 2019 - 16:55:45 EST


The rt5677 driver is using the wrong property names to read from ACPI.
Update the property names to match those from _DSD, so that the correct
GPIO pin numbers are read and that plug-detection works.

With this patch, plugging and unplugging the headphone jack switches
between headphones and speakers automatically.
