Various coding style fixes checkpatch warns about. The goal is not to be 100% checkpatch compliant, but to have more consistent coding style. As this is a trivial patch serie, will land in 24 hours in klibc git, unless of course ml review hits a bugger. Checked with size(3) that the generated kinit, fstype, ipconfig and nfsmount are the same. maximilian attems (4): [klibc] ipconfig: reduce
