From e4ca6cbd5c19e7e90b6b9c114f7364e603364842 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 2 Nov 2021 12:24:26 +0000 Subject: [PATCH] media: cec: copy sequence field for the reply commit 13cbaa4c2b7bf9f8285e1164d005dbf08244ecd5 upstream. When the reply for a non-blocking transmit arrives, the sequence field for that reply was never filled in, so userspace would have no way of associating the reply to the original transmit. Copy the sequence field to ensure that this is now possible.
