Subject: kasan: add kasan_tag_mismatch prototype
From: Arnd Bergmann <arnd@xxxxxxxx>
commit fb646a4cd3f0ff27d19911bef7b6622263723df6 upstream.
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.
