I suggest you paste the BUG info here to the commit too so it's clear
that this needs to go in as a fix. Also can you please describe how
this regression got introduced?

Other than that looks good to me as a fix for the -rc cycle. We could
add a struct for similar function pointers and SoC specific addresses,
but probably for the -rc cycle we should just keep this patch to the
minimum.
