From: William Dean <williamsukatube@xxxxxxxxx>
Because of the possible failure of the allocation, data->domains might
be NULL pointer and will cause the dereference of the NULL pointer
later.
Therefore, it might be better to check it and directly return -ENOMEM
without releasing data manually if fails, because the comment of the
devm_kmalloc() says "Memory allocated with this function is
automatically freed on driver detach.".
Fixes: a86854d0c599b ("treewide: devm_kzalloc() -> devm_kcalloc()")
