[PATCH v2 2/4] usb: xhci: xhci_mem_init: Use cpu_to_le64() and not xhci_writeq()

[Stefan Roese]

xhci_writeq() makes the CPU->LE swapping only when addressing registers
in the xHCI controller address range and not in the local memory (RAM).
We need to use cpu_to_le64() here to ensure that the conversion is done
correctly.
