Please provide code that links successfully, and compiles without 
obvious warnings.  pci_ioremap() does not exist; you wanted pci_iomap().

I applied the patch, fixed the obvious bugs, and then did my own line 
length, trailing whitespace, "if(" javaism, 'case' indentation, and 
other cosmetic cleanups.
