[alsa-devel] [PATCH] ASoC: WM8903: Add of_match_table

[Stephen Warren]

This allows the device to be matched against the device tree using the
compatible flag directly, as is standard, rather than falling back to
matching .id_table against the non-vendor portion of the first compatible
property value.
