Subject[PATCH 1/2] x86/speculation: add cpu_show_gds() prototype
Date
From: Arnd Bergmann <arnd@arndb.de>

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")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
