Subject: ACPI: move acpi_no_s4_hw_signature() declaration into #ifdef CONFIG_HIBERNATION
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9743fdea9f9473cd2440741342a5ed8e19eb51bd;p=linux-beck.git

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]
