Hi all,
These two patches are the culmination of the small discussion here:
https://lore.kernel.org/lkml/camuhmdvsdutoi5bugf9slqdgadwyl1+qalwskgin1teolgh...@mail.gmail.com/
I have fallen behind on fixing issues so sorry for not sending these
sooner and letting these warnings slip into mainline.

I have this patch in my local tree and debated sending it myself. I
think that this is the right fix for now, as the driver is being cleaned
up. Maybe add a FIXME like the rest of this driver?

I left out the default case since clang warns when a switch on an enum
does not handle all the values (compile time scream) versus a run time
scream like yours.
I don't have a preference for either so:
