Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hello All: "A module selects GENERIC_IRQ_CHIP and depend on IRQ_DOMAIN". For me, it is a reasonable selection and dependency, but "make allmodconfig" will report error. I guess it is the "Makefile allmodconfig" issue.
