[PATCH 5/8] ASoC: SOF: mediatek: remove error checks on NULL ipc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



mtk_adsp_ipc_get_data() can return NULL, but the value is not checked
before being used, leading to static analysis warnings.

sound/soc/sof/mediatek/mt8195/mt8195.c:90:32: error: dereference of
NULL ‘0’ [CWE-476] [-Werror=analyzer-null-dereference]

   90 |         spin_lock_irqsave(&priv->sdev->ipc_lock, flags);
      |                            ~~~~^~~~~~

It appears this is not really a possible problem, so remove those checks.
