[Qemu-ppc] [PULL 02/34] hw/ppc: use 0 instead of fdt_path_offset(fdt, "/


From: David Gibson
Subject: [Qemu-ppc] [PULL 02/34] hw/ppc: use 0 instead of fdt_path_offset(fdt, "/")
Date: Tue, 17 Oct 2017 15:21:20 +1100

From: Greg Kurz <address@hidden>

The offset of the root node is guaranteed to be 0.

This doesn't fix anything, it's just trivial cleanup of the two
remaining places where this was done under hw/ppc.
