Wysocki" , Len Brown Subject: [PATCH v2 0/2] Ignore bad graph port nodes on Dell XPS 9315 Date: Tue, 13 Feb 2024 15:46:04 +0200 Message-Id: <20240213134606.383817-1-sakari.ailus@linux.intel.com> X-Mailer: git-send-email 2.39.2 Precedence: bulk X-Mailing-List: linux-acpi@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Hi Rafael, These two patches skip instantiating bad port nodes on Dell XPS 9315. The ACPI firmware contains Linux specific camera declarations but they are missing the IVSC which sits between the camera and the IPU. The IPU bridge can be instead used to obtain a configuration that is usable in the system. I presume there are other models that have the same issue. since v1: - Use a better subject for the second patch. - Don't explicitly initialise static variable (second patch). - Improve the commit message of the second patch slightly.
