color_show() and fade_show callbacks use sprintf() to format sysfs output into the page buffer. Convert them to sysfs_emit(), which is the preferred helper for sysfs show() callbacks as it enforces page boundary checks. Similar conversions have already been made elsewhere in this subsystem (e.g. loopback.c, arche-platform.c).
