Subject: [14/18] xhci: xhci-hub: use port structure members instead of xhci_get_ports()
Date: Mon, 21 May 2018 16:40:02 +0300 [thread overview]
Message-ID: <1526910006-26104-15-git-send-email-mathias.nyman@linux.intel.com> (raw)
xhci_get_ports() is one of the last functions using port_arrays in
xhci-hub.c. We get the same data directly from hub and port structures
instead, so convert and remove both xhci_get_ports() and port_arrays from
all function that no longer need it.
