Re: [PATCH v2][next] hook: check for NULL pointer before deref

> Fix a compiler warning (-Werror=analyzer-deref-before-check) due to
> dereferencing the options pointer before NULL checking it.
>
> In practice run_hooks_opt() is never called with a NULL opt struct,
> so this just fixes the code to not trigger the warning anymore.
>
> The NULL check is kept as-is because some future patches might end up
> calling run_hooks_opt with a NULL opt struct, which is clearly a bug.
>
> While at it, also fix the BUG message function name.
