So the problem here is the "inherit linux-info xorg-2" line.
The xorg-2 eclass defines few default phase functions which you have
overridden.

If you want to patch the source you should be doing something like this:
src_prepare() {
	use debounce && epatch ${FILESDIR}/your-patch

	xorg-2_src_prepare # this will call the xorg-2 eclass
	#defined phase function to do the rest of the work
}

Alternatively, if you just want to apply that patch, you are probably
better off using epatch_user.
Drop your patch in
/etc/portage/patches/x11-drivers/xf86-input-evdev/your-name.patch
and the eclasses will automatically apply the patch. you do not have to
make your own ebuild just to apply the patch.
