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.
