Hi Alex,
My primary focus is the ath* wireless drivers, and my primary goal was 
to make the tables there const. So this series, along with the two 
out-of-series patches for ath10k and ath11k complete that scope of work.

The lack of the other changes to the QMI data structures is simply due 
to me not looking in depth at the QMI code beyond the registration 
interface.

I'll be happy to revisit this as a separate cleanup.
