[SRU][Trusty][lts-vivid][Wily][PATCH 0/1] Revert "usb: hub: do not clear BOS field during reset device"

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1582864

== SRU Justification ==
This bug is fixed by commit by upstream commit e5bdfd5, which reverts upstream 
commit d8f00cd.

With slub_debug enabled this manifests as a deref of 0x6b6b in usb_disable_ltm.

Without slub_debug you end up getting a double free and messing up the allocator 
and apparmor tends to be the first one to notice.  See stack trace in bug report.

    4.5.0-rc4 (current git)
    4.4.2
    4.3.6 (currently in review)
    4.1.18
    3.18.27
    3.14.61

This commit was also request in upstream kernels: v3.13.y-ckt, v3.19-ckt and v4.2.y-ckt.
