usb: fixes for v4.6-rc5
No more major fixes left. Out of the 6 fixes we have
here, 4 are on dwc3.
The most important is the memory leak fix in
dwc3/debugfs.c. We also have a fix for PHY handling
in suspend/resume and a fix for dwc3-omap's error
handling.
Suspend/resume also had the potential to trigger a
NULL pointer dereference on dwc3; that's also fixed
now.
Our good ol' ffs function gets a use-after-free fix
while the generic composite.c layer has a robustness
fix by making sure reserved fields of a possible SSP
device capability descriptor is cleared to 0.
