From caf0f4662e07fcc721d1c85af82aa8a7d57621f3 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Wed, 21 Dec 2022 12:23:20 +0200 Subject: [PATCH] ASoC: SOF: Add helper macro to be used to get an IPC ops In preparation to a case when the DSP is not used. In this case the IPC communication itself has no meaning and we might not even have sdev->ipc allocated at all. The sof_ipc_get_ops() macro can be used to get a named IPC ops struct or return NULL if the sdev->ipc is not allocated.
