Just because a parameter is called 'size' does not mean it should have type 'size_t'. In this case, it's a length of a (subset of a) BAR, and it can easily be 64-bit on a 32-bit kernel. Should probably be phys_addr_t (even though it's a length, not an address).

Logan just submitted v9 today. Perhaps comment on that with your size_t concerns. All input gratefully received ;-).
