Subject: [PATCH AUTOSEL 4.9 171/251] usb: host: xhci-hub: fix extra endianness conversion

From: Ruslan Bilovol <ruslan.bilovol@...il.com>

[ Upstream commit 6269e4c76eacabaea0d0099200ae1a455768d208 ]

Don't do extra cpu_to_le32 conversion for
put_unaligned_le32 because it is already implemented
in this function.

Fixes sparse error:
xhci-hub.c:1152:44: warning: incorrect type in argument 1 (different base types)
xhci-hub.c:1152:44:    expected unsigned int [usertype] val
xhci-hub.c:1152:44:    got restricted __le32 [usertype]

Fixes: 395f540 "xhci: support new USB 3.1 hub request to get extended port status"
