That's right. >>> CONFIG_RMI4_CORE=3Dm >>> CONFIG_RMI4_I2C=3Dm >>> CONFIG_RMI4_SPI=3Dm >>> # CONFIG_RMI4_SMB is not set > > This is your issue I believe. Indeed, enabling that configuration solves that issue. However, I think it is quite unintuitive that a module (psmouse) chooses a default mode which requires another driver which is not necessarily included; though it would probably be not a very clean solution to explicitly check that as well. Is this behaviour, that one module requires another without communicating that clearly, wanted?
