Yea, I did notice that also.  I just wanted to make sure I understood
what is going on so that I do not make the same mistake for the third

I did not use the SSP*_P functions because of the mess.  Actually at one
point the driver implemented register accesses in similar manner as
SSP*_P but David Brownell got me straightened out.  Thus the original
