So at boot, the functions are not there and the device is not properly populated. Force the functions to be embedded in rmi_core so that when the touchpad is there, the functions are there too. There is not much use of having the functions separate anyway Signed-off-by: Benjamin Tissoires --- drivers/input/rmi4/Kconfig | 5 +---- drivers/input/rmi4/Makefile | 2 +- drivers/input/rmi4/rmi_bus.c | 11 ++++++++++- drivers/input/rmi4/rmi_driver.h | 8 ++++++++ drivers/input/rmi4/rmi_f11.c | 10 +++++++++- 5 files changed, 29 insertions(+), 7 deletions(-) diff --git a/drivers/input/rmi4/Kconfig b/drivers/input/rmi4/Kconfig index d0c7b6e..5e3890e 100644 --- a/drivers/input/rmi4/Kconfig +++ b/drivers/input/rmi4/Kconfig @@ -37,7 +37,7 @@ config RMI4_I2C This feature is not currently available as a loadable module. config RMI4_F11 - tristate "RMI4 Function 11 (2D pointing)" + bool "RMI4 Function 11 (2D pointing)" depends on RMI4_CORE help Say Y here if you want to add support for RMI4 function 11. @@ -46,9 +46,6 @@ config RMI4_F11 touchpads.
