  From: Arnd Bergmann <arnd@arndb.de>

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.

Applied as 6.5 material, thanks!
