Argh, I forgot about that "issue".
Ok, let me go push out new releases with this reverted, and drop it from
the older stable kernels, as this isn't a good idea at the moment.
thanks,

Just for reference, I've also sent the following to the stable patch apply
notice:
"This commit reveals a few driver bugs resulting in deadlocks without the
following fixes:
- 1. ed1ac3c977dd ("iommu/arm-smmu-qcom: do not register driver in probe()")
- 2. 730e5ebff40c ("gpio: omap: do not register driver in probe()")
- 3. https://lore.kernel.org/lkml/20260212235842.85934-1-dakr@kernel.org/
The third one will hopefully be picked up by the clk folks soon.
(1) should be required since v6.11, (2) since (basically forever) v2.6.22 and
(3) since v5.11.
We should also consider that we do not know if (especially older) stable trees
have similar cases that we did not catch in linux-next."

One additional note, we want this commit backported regardless, as it also fixes
commit 0b4eeee2876f ("iommu/arm-smmu-qcom: Register the TBU driver in
qcom_smmu_impl_init").
I.e. the current code is racy in terms of async probe and the driver is never
unregistered even if built as module and the module is unloaded, which is a
potential UAF.
