Subject: x86/speculation: Add cpu_show_gds() prototype
Git-commit: a57c27c7ad85c420b7de44c6ee56692d51709dda
Patch-mainline: v6.5 or v6.5-rc6 (next release)
References: git-fixes
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.
Fixes: 8974eb588283b ("x86/speculation: Add Gather Data Sampling mitigation")
