Samuel, All,

On 2015-01-12 22:26 +0100, Samuel Martin spake thusly:

This does indeed fix the autobuild failure.

However (as discussed on IRC), the real fix is a bit more involved, as
our current libftdi is 0.19, but openocd requires 0.20:

    configure: WARNING: You need a newer libftdi version (0.20 or later)
    [...]
    MPSSE mode of FTDI based devices        no

But as you said, this is material for a further patch. So:

Tested-by: "Yann E. MORIN" <yann.morin.1998@free.fr>
Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

Regards,
Yann E. MORIN.
