Really? I do this and then I get this build error on x86:

drivers/slimbus/qcom-ngd-ctrl.c: In function âof_qcom_slim_ngd_registerâ:
drivers/slimbus/qcom-ngd-ctrl.c:1333:63: warning: dereferencing âvoid *â pointer
data = of_match_node(qcom_slim_ngd_dt_match, parent->of_node)->data;
^~
drivers/slimbus/qcom-ngd-ctrl.c:1333:63: error: request for member âdataâ in something not a structure or union


So I can't take this, something else must be wrong here...

thanks,
