File 0012-libtasn1-disable-code-not-needed-in-grub.patch of Package grub2
From 40099cf0d4d68e79db9e71d78070f37c73f998a0 Mon Sep 17 00:00:00 2001 From: Daniel Axtens <dja@axtens.net> Date: Fri, 1 May 2020 17:12:23 +1000 Subject: [PATCH 12/23] libtasn1: disable code not needed in grub We don't expect to be able to write ASN.1, only read it, so we can disable some code. Do that with #if 0/#endif, rather than deletion. This means that the difference between upstream and grub is smaller, which should make updating libtasn1 easier in the future. With these exclusions we also avoid the need for minmax.h, which is convenient because it means we don't have to import it from gnulib.
