[Qemu-devel] [PATCH 15/16] hw/dma/pl080: Remove hw_error() if DMA is enabled

[Peter Maydell]

The PL08x model currently will unconditionally call hw_error()
if the DMA engine is enabled by the guest. This has been
present since the PL080 model was edded in 2006, and is
presumably either unintentional debug code left enabled,
or a guard against untested DMA engine code being used.

Remove the hw_error(), since we now have a guest which
will actually try to use the DMA engine (the self-test
binary for the AN505 MPS2 FPGA image).
