That will work fine.

IIRC, a node name in fsl dts might appear to be "ssi@". I am currently out of town so cannot verify the patch. Fabio, would it be possible for you to run a boot test? Thanks Nicolin
[PATCH] ASoC: Use of_node_name_eq for node name comparisons
Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.
For the FSL ASoC card, the full node names appear to be "ssi", "esai",
and "sai", so there's not any reason to use strstr and of_node_name_eq
can be used instead.
