[GIT PULL] USB fixes for v4.4-rc3

[Felipe Balbi <balbi@ti.com>]

Hi Greg,

Here's my second round of fixes for current -rc as promissed.

Let me know if you want anything to be changed, but response
may be slow.

'vacation-mode' is a major mode which prevents emacs from being
used :-p

regards

usb: fixes for v4.4-rc3

Here's our second round of fixes. Some of the bugs are pretty old like
the one on pxa27x suspend implementation.

The most important part is a randbuild warning fix on MUSB CPPI DMA
engine by Arnd, a couple fixes by Felipe Tonello on f_midi (first one
makes sure we only transmit on enabled ep IN while second plugs a memory
leak) and a NULL pointer dereference fix on renesas usbhs.

Note that we also have a new compatible string being added for the MXS
PHY.
