14ff96e04c usb: renesas: pipe: convert a long if into a XOR operation
This is just a minor optimization for the long
if we have on the driver.

When we want to check that one input is true
and the other must be false, the bitwise XOR
operator will achieve that for us.

c1e4877a41 usb: renesas_usbhs: modify device attach method
Current renesas_usbhs had been assigning udev to each urb.
It was executed even though it was device0.
For this reason, the device0 had to set the new device address
which has still not been assigned. (it will be assigned on next step).
Current renesas_usbhs used fixed address for it.
but it is not good for USB hub support.
This patch modifies this issue.

7177aed44f usb: gadget: rename usb_gadget_driver::speed to max_speed
This commit renames the “speed” field of the usb_gadget_driver
structure to “max_speed”.  This is so that to make it more
apparent that the field represents the maximum speed gadget
driver can support.

This also make the field look more like fields with the same
name in usb_gadget and usb_composite_driver structures.  All
of those represent the *maximal* speed given entity supports.

After this commit, there are the following fields in various
structures:
* usb_gadget::speed - the current connection speed,
* usb_gadget::max_speed - maximal speed UDC supports,
* usb_gadget_driver::max_speed - maximal speed gadget driver
  supports, and
* usb_composite_driver::max_speed - maximal speed composite
  gadget supports.

87763842b7 usb: gadget: renesas_usbhs: Use kcalloc instead of kzalloc to allocate array
The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.
