[PATCH 1/4] /drivers/net ioremap balancing/returncode check (es3210.c)

[Scott Thompson]

patchset against 2.6.23-rc2 for /drivers/net ioremap balancing / 
return check:

  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.

I split patches up by file changed as each file had different 
'owner' to ease accept/reject/revision process.
