Subject: spapr_pci: use memory_region_add_subregion() with DMA windows
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5c3d70e9701402e2755cf5d43f62a305ade4def2;p=qemu.git

spapr_pci: use memory_region_add_subregion() with DMA windows

Passing a null priority to memory_region_add_subregion_overlap() is
strictly equivalent to calling memory_region_add_subregion().
