[ 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]
