[GIT PULL] USB fixes for v3.18-rc2

[Felipe Balbi]

Hi Greg,

Here's our first set of fixes for v3.18-rc cycle.

Quite a few goodies here but the most important is that most gadget drivers
(except for g_hid, g_midi and g_webcam) pass USB[23]0CV with MUSB and DWC3.

All patches have been tested for weeks (since v3.18 merge window opened) and
they have also been tested for a few days on top of v3.18-rc1.

Let me know if you want anything to be changed.

cheers

usb: fixes for v3.18-rc2

Here's the first set of fixes for v3.18-rc cycle. It includes
a whole bunch of bug fixes related to USB20CV and USB30CV when
running on DWC3 and MUSB. After this series, we have clean chapter 9
and MSC tests for all gadget drivers.

We also have a new PCI ID for Intel Braswell platform so they can use
DWC3 out-of-the-box.

A regression on functionfs wrt quirk_ep_out_aligned_size flag has also
been fixed.

DWC2 got a couple of fixes for the gadget role. The first of which fixes
rmmod followed by modprobe while the second makes sure to disable PHYs
before killing the regulators powering them.

These are the most important fixes worth mentioning, there are a few
other minor fixes as well.
