X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~13989^2~53

xend: Allow user to specify vslots 0 - 1f for static pass-through

The current parser only accepts vslots 0 - f (hex), that is, only
slots that have one digit. This is an omission as two digit slots
with a leading 0 or 1 are also valid, representing the
full range of slots 0 - 1f.

Thanks to Dexuan Cui for spotting this problem.
