Thank you @jyijyi very much! This solved the issue, now I can compile the drivers and find them under /sys/devices directory.

I did not have to change anything in `\linux_kernel_modules\mangoh\board_red_dv3.c.` or similar as you described. I pulled newest version from mangOH git, and there are no `i2c_get_adapter(0)` anymore. The `0` is replaced with some variable for each `i2c_get_adapter()`.

Is this something that will be fixed in later versions? Since I am working with both WP8548 and WP7702 I guess I need to change the `trigger.h` file accordingly to what module I am using?
