Input: synaptics-rmi4 - use sysfs_emit() to instead of scnprintf()
Replace calls to scnprintf() in the methods showing device attributes with sysfs_emit() to simplify the code. Signed-off-by: ye xingchen <ye.xingchen@zte.com.cn> Link: https://lore.kernel.org/r/202212011551429834598@zte.com.cn Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
