Reiterating my comment on patch 2/3, this code was fine until your patch 1/3 changed it declare a variable length array. Rather than creating a new patch to fix an earlier mistake in the same patch series, use "git rebase -i" to adjust patch 1/3 to not introduce the problem in the first place and drop this patch, and then (re-)submit the patch series.

Thanks.
