Merge tag 'fixes-for-v3.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
Felipe writes: usb: fixes for v3.19-rc6 The final set of fixes for v3.19. Two of the fixes are related to dwc3 scatter/gather implementation when we have more requests queued than available TRBs, while the other is a build fix for mv-usb PHY. Signed-off-by: Felipe Balbi <balbi@ti.com>
