I found some minor build issues in this series, which I'm just going
to fix up in my tree rather than making you respin this:


Format string issues which mean it doesn't build on OSX or 32-bit hosts:

/home/petmay01/linaro/qemu-for-merges/hw/display/xlnx_dp.c:700:5:
error: format ‘%lX’ expects argument of type ‘long unsigned int’, but
argument 3 has type ‘uint64_t’ [-Werror=format=]
/home/petmay01/linaro/qemu-for-merges/hw/display/xlnx_dp.c:709:5:
error: format ‘%lX’ expects argument of type ‘long unsigned int’, but
argument 3 has type ‘uint64_t’ [-Werror=format=]

Clang build issues:

/Users/pm215/src/qemu-for-merges/hw/i2c/i2c-ddc.c:284:33: warning:
unused variable 'vmstate_i2c_ddc' [-Wunused-const-variable]

(vmstate wasn't actually wired up to dc->vmsd)

/Users/pm215/src/qemu-for-merges/hw/dma/xlnx_dpdma.c:307:20: warning:
unused function 'xlnx_dpdma_set_desc_next_address' [-Wunused-function]
