Apparently the warnings show after commit
7d09e9725b5dcc8d14e101de931e4969d033a6ad, which explains that the warning is
triggered by "very likely a driver bug".

I don't know that this should have gone to stable. Looks like Sasha's bot
picked it up. I think it may depend on other ttm changes that are not in
stable.

Yeah, Alex is right this patch should have never been backported in the first
place.

Reverted in stable:
commit bec771b5e0901f4b0bc861bcb58056de5151ae3a
Author: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: Thu Mar 25 09:52:40 2021 +0100
Revert "drm/ttm: Warn on pinning without holding a reference"
This reverts commit 7d09e9725b5dcc8d14e101de931e4969d033a6ad which is
commit 57fcd550eb15bce14a7154736379dfd4ed60ae81 upstream.
It is causing too many warnings on 5.11.y, so should be dropped for now.
