Documentation/printk-formats.txtHi Micky,
Raw buffer as a hex string:
%*ph 00 01 02 ... 3f
%*phC 00:01:02: ... :3f
%*phD 00-01-02- ... -3f
%*phN 000102 ... 3f
For printing a small buffers (up to 64 bytes long) as a hex string with
certain separator. For the larger buffers consider to use
print_hex_dump().
Since we can't make sure the cnt value, it is not good use "%*ph",
because it must make cnt <= 64.
dw_len * 4 <= 64 ?
I think that in these two cases we can rely on print_hex_dump_bytes that
doesn't have the dev_dbg limit on buffer size.
Let me know what you think about it. If you agree, I can send a new version
for patches 3/4 and 4/4, since the first two have already been merged in the
linux-next tree by Greg.

Fabio
