Re: [PATCH v3 2/2] scripts: checkpatch: check unused parameters for function-like macro

[Charlemagne Lasse <charlemagnelasse@xxxxxxxxx>]

Hi,

Can this patch please be dropped from Linux-next (currently via
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm#mm-everything)?
It is obviously wrong when dealing with named variadic macro
parameters:
