PCI: designware: Use exact access size in dw_pcie_cfg_read()
dw_pcie_cfg_write() uses the exact 8-, 16-, or 32-bit access size requested, but dw_pcie_cfg_read() previously performed a 32-bit read and masked out the bits requested. Use the exact access size in dw_pcie_cfg_read(). For example, if we want an 8-bit read, use readb() instead of using readl() and masking out the 8 bits we need. This makes it symmetric with dw_pcie_cfg_write(). [bhelgaas: split into separate patch, set *val = 0 in failure case] Signed-off-by: Gabriele Paoloni <gabriele.paoloni@huawei.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
