[ Upstream commit c2f0cbb57dbac6da3d38b47b5b96de0fe4e23884 ]
Tha parent node of "wcd_codec" specifies #address-cells = <1> and #size-cells = <0>, which means that each resource should be described by one cell for the address and size omitted.
However, wcd_codec currently lists 0x200 as second cell (probably the size of the resource). When parsing this would be treated like another memory resource - which is entirely wrong.
To quote the device tree specification [1]: "If the parent node specifies a value of 0 for #size-cells, the length field in the value of reg shall be omitted."
