[Xen-devel] [PATCH v4 43/53] xen/arch/x86/hvm/viridian.c: remove custom_param() error messages

[Juergen Gross <jgross@xxxxxxxx>]

With _cmdline_parse() now issuing error messages in case of illegal
parameters signalled by parsing functions specified in custom_param()
the message issued by parse_viridian_version() can be removed.
