Your commit message is still incomplete as it does not really say anything about what this patch does, why this is needed or what the implications are if not merging this patch.
How would one determine that this patch is a valid candidate for backporting, for example.

If this is so obviously correct, why isn't this flag set for LLCC_WRCACHE for all the SoCs?

The other SoCs where it's disabled (8180 and 8150) have it in line with the recommendations.

If you don't know what this slice is used for or what impact enabling it has then saying so in the commit message is also useful information.
But you should be able to provide some background for reviewers, stable maintainers, other devs, posterity, ...

I'm sure the patch is correct, but spell something out in the commit message.
