ASoC: sta529: Add OF device ID table
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. Before this patch: $ modinfo sound/soc/codecs/snd-soc-sta529.ko | grep alias alias: i2c:sta529 After this patch: $ modinfo sound/soc/codecs/snd-soc-sta529.ko | grep alias alias: of:N*T*Cst,sta529C* alias: of:N*T*Cst,sta529 alias: i2c:sta529 Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Mark Brown <broonie@kernel.org>
