I have added this fix up patch to linux-next today (more or less - this
is a hand hacked version, but you get the idea):
From: Stephen Rothwell <s...@canb.auug.org.au>
Date: Wed, 1 Feb 2023 13:13:01 +1100
Subject: [PATCH] i915: fix up for "drm/i915: Fix up locking around dumping
requests lists"
interacting with "i915: Move list_count() to list.h as list_count_nodes() for
broader use"
Signed-off-by: Stephen Rothwell <s...@canb.auug.org.au>
