HID: fix hid-ff drivers so that devices work even without ff support
Currently, the hid-*ff force feedback drivers, which claim the blacklisted device on a HID bus, are only compiled in if the user selects force feedback support. However we want the device to be supported even when the kernel is configured without force feedback. This patch fixes the drivers in a way that they get compiled even if force feedback is turned off; all the force feedback support code is compiled out in such case, and the driver works as a usual driver on HID bus, claiming and initializing the device, making it operational without FF effects. Reported-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
