Patches 2 and 3 of this series depend on patch 1. Since patch 3 contains
the bulk of the changes, I based this series on the drm-next tree.
However, patch 2 has a conflict elswhere in the tree, which did not
appear until 6.2-rc1. At the time I sent out this series, drm-next did
not contain this commit, and I couldn't find it based on Robin's
description [1], so now we end up with a conflict. As this commit has
now been merged into drm-next, I can rebase and resend if there are no
other comments.

Right it doesn't affect DRM, and was merged via the IOMMU tree, but it 
does affect *this* patch, which Sean has based on a drm-next branch that 
seemingly still wasn't up to date with 6.2-rc1 at the time.

Since v2 had already been posted, it seemed like a bright idea to 
comment here to clarify that it was still relevant, rather than bumping 
the old thread to reply directly. Apologies for any confusion.

In practical terms I think it's merely a case of dropping this hunk; the 
other one in mtk_iommu_v1.c looks fine to me.

Cheers,
Robin.
