[PATCH] ACPI: s2idle: fix section mismatch warning

From: Arnd Bergmann
Date: Thu Jun 01 2023 - 17:33:30 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

The acpi_sleep_suspend_setup() function is missing an __init annotation,
which causes a warning in rare configurations that end up not inlining
it into its caller:

WARNING: modpost: vmlinux.o: section mismatch in reference: acpi_sleep_suspend_setup (section: .text) -> acpi_s2idle_setup (section: .init.text)

It's only called from an __init function, so adding the annotation is
correct here.
