[PATCH 3/3] /drivers/net ucc_geth ioremap balancing/returncode check (resend)

resending patchset against 2.6.23-rc3 for /drivers/net ioremap balancing / return check,
previous patchset contained wordwrap errors:

  corrects:
  --sbus_ioremap return unchecked.
  --ioremap function unchecked
  --function failure cases did not clean up ioremap'd values.
  lne390.c  -- believe had incorrect/not ideal variable check on if for iounmap

this audit was only for files directly in drivers/net directory, not the full tree.
