[Qemu-devel] [PULL 76/79] hw/nvram/fw_cfg: Use memberwise copy of MemoryRegionOps struct

[Paolo Bonzini]

From: Peter Maydell <address@hidden>

We've now removed the 'old_mmio' member from MemoryRegionOps,
so we can perform the copy as a simple struct copy rather
than having to do it via a memberwise copy.
