pinctrl: tb10x: Use flexible-array member and struct_size() helper Update the code to use a flexible array member instead of a pointer in structure tb10x_pinctrl and use the struct_size() helper: struct tb10x_pinctrl { ... struct tb10x_of_pinfunc pinfuncs[]; }; Also, make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(struct tb10x_pinctrl) + of_get_child_count(of_node) * sizeof(struct tb10x_of_pinfunc) with: struct_size(state, pinfuncs, of_get_child_count(of_node)) This code was detected with the help of Coccinelle.
