Pull USB fixes from Greg KH:
 "Here are a few USB fixes for 4.5-rc6

  They fix a reported bug for some USB 3 devices by reverting the recent
  patch, a MAINTAINERS change for some drivers, some new device ids, and
  of course, the usual bunch of USB gadget driver fixes.

  All have been in linux-next for a while with no reported issues"

*
* The assignment of transfer resources cannot perfectly follow the
* data book due to the fact that the controller driver does not have
* all knowledge of the configuration in advance. It is given this
* information piecemeal by the composite gadget framework after every
* SET_CONFIGURATION and SET_INTERFACE. Trying to follow the databook
* programming model in this scenario can cause errors. For two
* reasons:
*
* 1) The databook says to do DEPSTARTCFG for every SET_CONFIGURATION
* and SET_INTERFACE (8.1.5). This is incorrect in the scenario of
* multiple interfaces.
*
* 2) The databook does not mention doing more DEPXFERCFG for new
* endpoint on alt setting (8.1.6).
*
* The following simplified method is used instead:
*
* All hardware endpoints can be assigned a transfer resource and this
* setting will stay persistent until either a core reset or
* hibernation. So whenever we do a DEPSTARTCFG(0) we can go ahead and
* do DEPXFERCFG for every hardware endpoint as well. We are
* guaranteed that there are as many transfer resources as endpoints.
*
* This function is called for each endpoint when it is being enabled
* but is triggered only when called for EP0-out, which always happens
* first, and which should only happen in one of the above conditions.
