This driver wants to access these structures as arrays of uint32_t.
It used to cast directly, but that isn't allowed. So, I've passed
the cast through a (void *). Is that allowed? Eg:

struct foo foo;
((uint32_t *)(void *)&foo)[3] = 12;

is that OK?
I'm afraid that only silences the warning without solving the underlying
problem. I don't think there's a Standard conforming way to treat a
struct foo as an uint32_t array.

A union should do the trick.
