usb: xhci-pci: Check for errors from dm_pci_map_bar() Function dm_pci_map_bar() may fail and returns NULL. Check this to prevent dereferencing a NULL pointer. In xhci-pci this may happen when board does not enable CONFIG_PCI_PNP and PCI_BASE_ADDRESS_0 contains unconfigured zero address. Signed-off-by: Pali Rohár <pali@kernel.org>
