cfba5de9b99f drivers: Introduce device lookup variants by of_node
this looks suspicios to me since the change is in the function which fails:
struct regulator_dev *of_find_regulator_by_node(struct device_node *np) { struct device *dev; - dev = class_find_device(®ulator_class, NULL, np, of_node_match); + dev = class_find_device_by_of_node(®ulator_class, np);
but i cannot revert this commit so i did it manually...but this does not seem to be the cause...still error 517, also a change in core.c is not the cause...
how can i check instantiation at runtime?
regards Frank
