Subject: [PATCH] media: intel/ipu6: Set the VC of the stream as the SOF event id
Date: Thu, 24 Oct 2024 11:22:01 +0800 [thread overview]
Message-ID: <20241024032201.3867638-1-hongju.wang@intel.com> (raw)
In the virtual channel case, they should use v4l2_event.id to distinguish
SOF events of different streams. Therefore, we set the virtual channel
number of the stream as the SOF event ID. This number is unique.
