[alsa-devel] [PATCH] Add rudimentary device tree support for SSM2518
For some reason the SSM2518 codec driver doesn't have DT support, even though there are bindings described for it in Documentation/devicetree/sound/ssm2518.txt . This patch adds rudimentary DT support for the compatible property which is a step forward.

Patch looks mostly good, but make sure to use a patch subject that follows the general style of the subsystem you are sending the patch for. In this case it should be something like:
ASoC: ssm2518: Add rudimentary device tree support
Also make sure that when you send a patch to add the maintainers of the subsystem to your receiver list, so they'll see the patch can pick it up. In this case that is Mark and Liam
One issue inline.

If you use of_match_ptr() you don't need the #ifdef CONFIG_OF, so just drop the two lines.
