Message-ID: <20260916124513.BBD8A1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260916-topic-pcie_portrec_enodev-v1-1-5dc7bde39552@oss.qualcomm.com>
> Root Port recovery may race with a device hot-unplug. In that case,
> dw_pcie_wait_for_link() returns -ENODEV because no device is detected
> after the controller has been successfully reset.
>
> This is a valid outcome and should not cause Root Port recovery to
> fail. Ignore -ENODEV while continuing to propagate other link-training
> errors.
