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. Tested-by: Kuninori Morimoto <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

2011-12-13usb: renesas_usbhs: modify device attach methodKuninori Morimoto1-28/+69
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.

2011-12-12usb: gadget: rename usb_gadget_driver::speed to max_speedMichal Nazarewicz1-1/+1
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.
