From: Arnd Bergmann Date: Wed, 9 Aug 2023 13:04:59 +0000 (+0200) Subject: x86/speculation: Add cpu_show_gds() prototype X-Git-Tag: v6.1.52~448 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f276899f8dbc882dfa634a384ca86e056088dbde;p=platform%2Fkernel%2Flinux-starfive.git x86/speculation: Add cpu_show_gds() prototype commit a57c27c7ad85c420b7de44c6ee56692d51709dda upstream. The newly added function has two definitions but no prototypes: drivers/base/cpu.c:605:16: error: no previous prototype for 'cpu_show_gds' [-Werror=missing-prototypes] Add a declaration next to the other ones for this file to avoid the warning.
