Asking Linus directly often is fine, if it's something urgent and the
maintainer that usually would handle a patch is MIA. But in this
particular case it's likely not the best strategy, as it seems
753395ea1e45 was merged via the ARM soc tree. In that case I'd say the
revert should ideally go through there as well, hence I'd suggest asking
those maintainers (e.g. Arnd and Olof) is the right move at this point
in time (would be something different if today was release day; but even
then it would be wise to have them involved).

Ciao, Thorsten
