Subject: [PATCH 13/21] media: ipu6: Avoid accessing av->streams before streaming
Date: Mon, 14 Sep 2026 23:53:50 +0300 [thread overview]
Message-ID: <20260914205358.735307-14-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20260914205358.735307-1-sakari.ailus@linux.intel.com>
Streams will soon be allocated just for the duration of streaming
operation. In this case, obtain the CSI-2 sub-device through av->csi2
which is set up during driver probe.
