Possibly true, but %*ph doesn't emit ascii nor
does it format a large block of data very well.
Maybe use of
pr_debug("%*ph", len, buf)
vs
print_hex_dump_bytes("prefix", DUMP_PREFIX_<STYLE>, buf, len)
could be described a bit in dynamic_debug_howto
or perhaps all of the various printk, dev_<level>,
<subsystem>_<level> styles and all the various
debugging options would be better described in a
new printk_howto
