When the driver was updated to be endian neutral (8e9c7716c)
the signed part of the s16 values was lost. This is because be16_to_cpu()
returns a signed value. This patch casts the values back to a s16 number
prior to the the implicit cast up to an int.

Seems the comment has a error. Should be 'returns an unsigned' rather than signed. Other than that it looks good.
