Accept >= 0 return values of the ioctl() to figure out the device name.

	* modules/controller_linux_input.c: Accept >= 0 return values of the
	ioctl() to figure out the device name. Apparently it is the number of
	bytes written to the string, so we might omit the strlen() following,
	but I don't like to rely on that...
