[PATCH 2/2] hw/pci/pci_host: Let pci_data_[read/write] use unsigned 'size' argument |
Date: |

Both functions are called by MemoryRegionOps.[read/write] handlers
with unsigned 'size' argument. Both functions call
pci_host_config_[read/write]_common() which expect a uint32_t 'len'
parameter (also unsigned).
Since it is pointless (and confuse) to use a signed value, use a
unsigned type.
