3.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kishon Vijay Abraham I <kis...@ti.com>
commit 066618bc350cc6035c3a0fc559a8ac02f55785a9 upstream.
Populate the resources for xhci afresh instead of directly using the
*struct resource* of core. *resource* structure has parent, sibling,
child pointers which should be filled only by resource API's. By
directly using the *resource* pointer of core in xhci, these parent,
sibling, child pointers are already populated even before
*platform_device_add* causing side effects.
