File 0006-libgcrypt-Declare-the-sha256-shaext-function.patch of Package grub2
From 09f3b0e95d51338fb1e18e7e79bce60a6d22de8d Mon Sep 17 00:00:00 2001 From: Gary Lin <glin@suse.com> Date: Fri, 18 Jul 2025 15:45:02 +0800 Subject: [PATCH 6/8] libgcrypt: Declare the sha256 shaext function There is no prototype of _gcry_sha256_transform_intel_shaext() defined in the header or libgcrypt-grub/cipher/sha256.c, and gcc may complain the missing-prototypes error when compiling sha256-intel-shaext.c. Declare the prototype in sha256-intel-shaext.c to avoid the error.
