Subject: [PATCH 04/11] ASoC: SOF: pcm: Extend the optionality of IPC ops to IPC as well
Date: Wed, 21 Dec 2022 12:23:21 +0200	[thread overview]
Message-ID: <20221221102328.9635-5-peter.ujfalusi@linux.intel.com> (raw)
In-Reply-To: <20221221102328.9635-1-peter.ujfalusi@linux.intel.com>

The IPC ops are optional, but they require that the ops struct is to be
allocated with all callbacks set to NULL.

Update the code to extend the optionality to:
sdev->ipc == NULL
sdev->ipc->ops == NULL
sdev->ipc->ops->[pcm] == NULL
sdev->ipc->ops->[pcm]->ops == NULL (treated optional currently)
