Subject: pci: pass along the return value of dma_memory_rw
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=195cc354696d75e9625cf303a0791404b3215501;p=qemu.git

pci: pass along the return value of dma_memory_rw

Some devices might want to know the return value of dma_memory_rw, so
pass it along instead of ignoring it.

There are no existing users of the return value, so this patch should be
safe.
