The quilt patch titled
     Subject: kasan: add kasan_tag_mismatch prototype
has been removed from the -mm tree.  Its filename was
     kasan-add-kasan_tag_mismatch-prototype.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

------------------------------------------------------
From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: kasan: add kasan_tag_mismatch prototype
Date: Tue, 9 May 2023 16:57:20 +0200

The kasan sw-tags implementation contains one function that is only called
from assembler and has no prototype in a header.  This causes a W=1
warning:

mm/kasan/sw_tags.c:171:6: warning: no previous prototype for 'kasan_tag_mismatch' [-Wmissing-prototypes]
  171 | void kasan_tag_mismatch(unsigned long addr, unsigned long access_info,

Add a prototype in the local header to get a clean build.
