There are some users ask for this patch can be applied on 2.6.18.x. This is
they want.
In fact, this patch for 2.6.17.7, also can be applied on 2.6.17.6, 2.6.17.8,
2.6.17.9 without any warning and error.
Moreover, it can be used for 2.6.18-rc4, but patch program will tell us some
warning information.
Another patches:
[PATCH] usb: Betop BTP-2118 joystick force-feedback driver 20060817
[PATCH] usb: HID Simple Driver Interface 0.3.1 (Kconfig and Makefile) 20060817
[PATCH] usb: Microsoft Natural Ergonomic Keyboard 4000 Driver 0.3.1
They all can be patched on 2.6.18-rc4 fine without any change. Of course, you
should use patch with -p1 option, not -p0.
