Subject[PATCH v2 3/3] ASoC: rt5677: fall back to DT prop names on error
Date
The rt5677 driver uses ACPI-style property names to read from the
device API. However, these do not match the property names in _DSD
used on the Chromebook Pixel 2015, which are closer to the Device Tree
style. Unify the two functions for reading from the device API so that
they try ACPI-style names first and fall back to the DT names on error.
