WTF.  OK, this is clearly my fault.  I went back to the exact patch
and it didn't compile for me, either.  :(  My typical workflow is to
develop something in our local tree and then cherry-pick (and test!)
on ToT linux.  Probably what happened in this case was that there was
a compile error and I didn't notice and somehow ended up testing my
local tree (which doesn't error-check mmc_add_host).

Sorry for the hassle.  Leaving the err_setup_bus in is correct (and
leaving the "ret" variable declared).

I did those fixups and it now compiles and things boot.  I haven't
tested the deferral case in ToT yet, though.  I'll try that now and
post if something weird comes up.
