From cb94ff5f80c537e43c04fa4f071f1df784255310 Mon Sep 17 00:00:00 2001 From: Martin Kletzander Date: Mon, 2 Oct 2023 16:27:57 +0200 Subject: audio: propagate Error * out of audio_init Starting from audio_driver_init, propagate errors via Error ** so that audio_init_audiodevs can simply pass &error_fatal, and AUD_register_card can signal faiure.
