xhci: pass port pointer as parameter to xhci_set_port_power()
Pass the port structure pointer directly to xhci_set_port_power() instead of hcd and port index. cleanup Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20230202150505.618915-7-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
