ACPI: move acpi_no_s4_hw_signature() declaration into #ifdef CONFIG_HIBERNATION
acpi_no_s4_hw_signature is defined in #ifdef CONFIG_HIBERNATION block, but the current code put the declaration in #ifdef CONFIG_PM_SLEEP block. I happened to meet this issue when I turned off PM_SLEEP config manually: arch/x86/kernel/acpi/sleep.c:100:4: error: implicit declaration of function ‘acpi_no_s4_hw_signature’ [-Werror=implicit-function-declaration] Signed-off-by: Yuanhan Liu <yuanhan.liu@linux.intel.com> Reviewed-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
