I agree with Marjin the log of the failure isn't required.
How about this as a commit log ?
"The GPU currently fails to initialise because the adreno_smmu node is
missing. We require the adreno_smmu node to translate device virtual
addresses properly.
Enable it now."

I'd drop that, we know the fix works.
Fixes: 87cd46d68aeac8 ("Configure Adreno GPU and related IOMMU")
Retain this though, its a legitimate fix the GPU won't work without this
change.
Then add
