[PATCH 034/145] usb: host: xhci-plat: release mem region while removing module

[Kamal Mostafa]

3.8.13.5 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: George Cherian <george.cherian at ti.com>

commit 5388a3a5faba8dfa69e5f06c3a415d373c1a4316 upstream.

Do a release_mem_region of the hcd resource. Without this the
subsequent insertion of module fails in request_mem_region.
