Change the error message directly in\nmtk_dp_wait_hpd_asserted() to dev_err() to avoid this. Also change the\nerror messages in mtk_dp_parse_capabilities(), which is called by\nmtk_dp_wait_hpd_asserted().\n\nWhile touching these prints, also add the error code to them to make\nfuture debugging easier.\n\ud83d\udccf Published: 2025-04-18T07:01:32.338Z\n\ud83d\udccf Modified: 2025-04-18T07:01:32.338Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/13ec849fd2eab808ee8eba2625df7ebea3b85edf\n2. https://git.kernel.org/stable/c/57a9fb47551b33cde7b76d17c0072c3b394f4620\n3. https://git.kernel.org/stable/c/2fda391ef7a701748abd7fa32232981b522c1e07\n4. https://git.kernel.org/stable/c/149a5c38436c229950cf1020992ce65c9549bc19\n5. https://git.kernel.org/stable/c/106a6de46cf4887d535018185ec528ce822d6d84", "creation_timestamp": "2025-04-18T07:59:16.000000Z"}
