i2c: mux: Remove class argument from i2c_mux_add_adapter()
99a741aa7a2d ("i2c: mux: gpio: remove support for class-based device instantiation") removed the last call to i2c_mux_add_adapter() with a non-null class argument. Therefore the class argument can be removed. Note: Class-based device instantiation is a legacy mechanism which shouldn't be used in new code, so we can rule out that this argument may be needed again in the future.
