[uml-devel] [patch] kernel cmd line parser fix

[Gerd Knorr <kraxel@bytesex.org>]

  Hi,

This patch passes up the line_setup return value.  That makes
the kernel try the next __setup() handler in case line_setup
didn't manage to parse the argument, which is especially
important for the "console=ttyS0" argument (which is simply
ignored without this patch).
