[Xen-devel] [PATCH 1/1] xen/arm: Use "" instead of "/" for domU root node.

[Will Abele <will.abele@xxxxxxxxxx>]

From: Will Abele <will.abele@xxxxxxxxxx>

Prior to linux a7e4cfb0a7ca4773e7d0dd1d9c018ab27a15360e
(merged in 4.15), Linux checked to see if the device tree version was
greater than 0x10 by checking for a root node "/". Xen creates a version
0x11 device tree, so the root node's unit name should be "".
