Input: synaptics-rmi4 - fix enum_fmt
Do not enumerate all formats, some of which the device may not even support. Instead, only report the one fixed format of the currently selected input that will survive try_fmt/s_fmt. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
