Please use full argument names

#define pr_emerg_hex_dump(prefix_str, prefix_type,			\
			  rowsize,  groupsize,	buf, len, ascii)	\
	print_hex_dump(KERN_EMERG, prefix_str, prefix_type,
		       rowsize, groupsize, buf, len, ascii)

etc...

Perhaps prefix_str should be pr_fmt(prefix_str)

As these macros are not yet in use anywhere, I think
that pr_warning_hex_dump should not be defined and
that pr_warn_hex_dump is sufficient and compatible
with the current use styles in dev_<level> and others.

pr_cont_hex_dump should not be defined.
