Hello, I was trying to work with the iio dummy driver, and when I try to load the iio_dummy_evgen.ko module I am getting unknown symbols found in module error on running modprobe. These variables are unknown iio_bus_type irq_sim_init irq_sim_fini irq_sim_fire irq_sim_fini All of these variables are present in the Module.symvers file in the /lib/modules/<kernel version>/build directory. The kernel and the modules versions match. I ran make clean, make, and make modules_install before trying to load them. I am unable to figure out the problem. Where I might be going wrong any ideas ?
