Subject: [PATCH v2 1/2] ASoC: Remove 'const' from the device_node pointers

>From Russell King:
of_node_put() modifies the struct device_node contents.  Therefore,
of_node_put() definitely not treating the data pointed to as read-only,
and therefore it is completely inappropriate for it to be marked "const".
