After David had a look, he told me unmap would never happen because the loop range is empty. So we should change this description with this: " On failure before assigning maps, it was trying to unmap. The compiler should have detected that the unmap loop is a nop. The fix is changing the goto destination after unmapping to allow compiling with "minsize" option. " Because it is not fixing anything but minsize build, the title should be "bus/pci: fix minsize build"
