Please use normal goto unwinding so the driver follows the same model
as almost all other pci drivers and allows people to follow your driver
more easily. Also it's not a alot of cleanup code, so removing this
might actually be a net decrease in lines of code.

Please give all your function a nice prefix so that oops messages are
more readable.
