Date: Tue, 29 Aug 2023 13:24:28 +0800 Message-Id: <1693286668-13055-4-git-send-email-wentong.wu@intel.com> X-Mailer: git-send-email 2.7.4 In-Reply-To: <1693286668-13055-1-git-send-email-wentong.wu@intel.com> References: <1693286668-13055-1-git-send-email-wentong.wu@intel.com> Precedence: bulk List-ID: X-Mailing-List: linux-media@vger.kernel.org During probe ivsc ace device, acpi_dev_clear_dependencies() will be called to clear the consumer and supplier relationship between camera sensor device and ivsc device. But IPU bridge will setup the connection swnodes for ivsc device and camera sensor device based on this consumer and supplier relationship. This patch defers ivsc ace's probe to make sure IPU bridge is initialized before this consumer and supplier relationship between camera sensor device and IVSC device is cleared.
