I did up a patch set yesterday that fixes most of the Sparse
warnings. It was simply a matter of changing all struct members in
ks_hostif.h to be __leXX and adding a few cpu_to_leXX()/leXX_to_cpu()
calls. Exactly as you did. I'm going to wait for your patch, and
another that is in flight on ks7010, to be merged before I submit
it. There will still be a few Sparse warnings that are a little more
tricky, so there is still some fun to be had.
