Description
A vulnerability in the Linux kernel's ASoC fsl_audmix driver causes system hangs due to register writes targeting unpowered hardware between probe initialization and the first runtime resume. This occurs because the AUDMIX block remains powered off after pm_runtime_enable() until the first runtime resume. The issue is fixed by powering up the hardware immediately after enabling runtime PM and handling cases where runtime PM is disabled.
