Several fixes based on customer feedback: * WHO_AM_I value has changed since preliminary parts used for initial testing; * Output of le16_to_cpu must be saved to memory before shifting to preserve sign; * Initial data rate was not extracted from data control register init. This was causing the initial data rate to be set to maximum until it was changed. To fix this problem, it made more sense to specify initial data rate and extract the register mask from that.
