SubjectRe: [PATCH 1/2] vsprintf: Add %pMbt, bluetooth mac address
From
2010/12/4 Joe Perches <joe@perches.com>:
> Bluetooth output the MAC address in reverse order.
> Bluetooth memory order: 00 01 02 03 04 05 is output "05:04:03:02:01:00".
>
> This can save overall text when bluetooth is compiled in.
>
> Bluetooth currently uses a very slightly unsafe local function (batostr)
> to output these formatted addresses.
>
> Adding %pMbt allows the batostr function to be removed.

Just a nitpick:
You could call it %pMR, as in 'Reverse', so it sounds better when/if
some other subsystem uses it. It would also be a hint of what is this
doing instead of where it came from.

Best Regards,
