Krzysztof Opasiak b282a118eb usbip: vudc: Refactor init_vudc_hw() to be more obvious
Current implementation of init_vudc_hw() adds ep0 to ep_list
and then after looping through all endpoints removes it from
that list.

As this may be misleading let's refactor this function
and avoid adding and removing ep0 to eplist and place it
immediately in correct place.

In addition let's remove redundant 0 assignments as ep
array is zeroed during allocation.

Greg Kroah-Hartman ae4d814bf1 usb: patches for v4.10 merge window
One big merge this time with a total of 166 non-merge commits.
 
 Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far
 second (22.5%). The remaining 9.3% are scattered on gadget drivers.
 
 The most important changes for dwc2 are the peripheral side DMA support
 implemented by Synopsys folks and support for the new IOT dwc2
 compatible core from Synopsys.
 
 In dwc3 land we have support for high-bandwidth, high-speed isochronous
 endpoints and some non-critical fixes for large scatter lists.
 
 Apart from these, we have our usual set of cleanups, non-critical fixes,
 etc.

Felipe Balbi 14f91dd524 usb: ip: remove unnecessary & operation
Now that usb_endpoint_maxp() only returns the lowest
11 bits from wMaxPacketSize, we can remove the &
operation from this driver.

Krzysztof Opasiak 2bdf6ea51c usb: usbip: vudc: Fix WARN_ON() usage pattern
Fix WARN_ON() macro usage as suggested by Felipe.
Instead of using:
if (cond) {
   WARN_ON(1);
   do_stuff();
}

Use a better pattern with WARN_ON() placed in if condition:

if (WARN_ON(cond))
   do_stuff();
