The approach currently being taken doesn't look sparse-compliant. You should write an le16 into a __le16 member; writing a cpu16 into a __le16 member and then converting in place using cpu_to_le16() is broken.

The above jumped out at me while scanning your patch -- it failed my mental pattern matching.
