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.

Felipe writes: 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.
Now that usb_endpoint_maxp() only returns the lowest 11 bits from wMaxPacketSize, we can remove the & operation from this driver.

As find_endpoint() is a global funcion rename it to vudc_find_endpoint() to clearly mark where does it come from. Signed-off-by: Krzysztof Opasiak <k.opasiak@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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();

Add endpoints definitions and ops for both endpoints and gadget.
Add also a suitable platform driver and functions for handling
usbip events.
