Merge tag 'fixes-for-v3.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
usb: fixes for v3.16-rc2 dwc3-omap won't crash anymore on module removal and suspend/resume won't kill xHCI interrupts. MUSB got a fix to handle Babble condition only in host mode, how it should be. The f_fs function driver got a fix for a NULL pointer dereference. Renesas gadget got a fix for Status stage handling. Signed-of-by: Felipe Balbi <balbi@ti.com>
