From: Arnd Bergmann Date: Wed, 9 Aug 2023 13:05:00 +0000 (+0200) Subject: x86: Move gds_ucode_mitigated() declaration to header X-Git-Tag: v6.1.52~447 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=19e7feda89667d01b77e84d6e7a02700106a4ae2;p=platform%2Fkernel%2Flinux-starfive.git x86: Move gds_ucode_mitigated() declaration to header commit eb3515dc99c7c85f4170b50838136b2a193f8012 upstream. The declaration got placed in the .c file of the caller, but that causes a warning for the definition: arch/x86/kernel/cpu/bugs.c:682:6: error: no previous prototype for 'gds_ucode_mitigated' [-Werror=missing-prototypes] Move it to a header where both sides can observe it instead.
