From 1a48e2ccd4385caa9ad9659ac8f9d75affacc9da Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 9 Aug 2023 23:10:50 +0200 Subject: [PATCH] m68k: Add memcmp() declaration There is a global definition of memcmp() that gets built on m68k but is never used and causes a warning because of the missing prototype: lib/string.c:671:15: error: no previous prototype for 'memcmp' [-Werror=missing-prototypes] Add the corresponding declaration to avoid the warning.
