Alice Ryhl 8121353a4b rust: regulator: do not assume that regulator_get() returns non-null ... The Rust `Regulator` abstraction uses `NonNull` to wrap the underlying `struct regulator` pointer. When `CONFIG_REGULATOR` is disabled, the C stub for `regulator_get` returns `NULL`. `from_err_ptr` does not treat `NULL` as an error, so it was passed to `NonNull::new_unchecked`, causing undefined behavior. Fix this by using a raw pointer `*mut bindings::regulator` instead of `NonNull`. This allows `inner` to be `NULL` when `CONFIG_REGULATOR` is disabled, and leverages the C stubs which are designed to handle `NULL` or are no-ops.
