Aside from a couple of "expression using sizeof(void)" messages that I 
haven't been able to fully clean out, yes, the driver builds pretty 
clean with sparse.  In this particular case, I think the typecast stops 
the complaint that you are expecting here.  But yes, these would be 
better off with le32_to_cpu().
