Hey Andy.

The conversions are not all the same.
One uses "%*ph", the others use "%*phC"
even though all origin hex formats are "%x:%x:..."
Ideally all the conversions would use the same format style.

Uses "%*ph"
You removed a newline.
That should probably be mentioned in the changelog.

It would be a bit nicer as well to align the arguments
after the open paren like:

	RT_TRACE(rtlpriv, COMP_SEC, DBG_LOUD, "key_cont_128: %*ph\n",
		 6, key_cont_128);

Uaes "%*phC", etc...
