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.
