[Qemu-devel] [PATCH] acpi: initialize s4_val used in s4 shutdown

[Bruce Rogers <brogers@suse.com>]

While investigating why a 32 bit Windows 2003 guest wasn't able to
successfully perform a shutdown /h, it was discovered that commit
afafe4bbe0cf7d3318e1ac7b40925561f86a6bd4 inadvertently dropped the
initialization of the s4_val used to handle s4 shutdown.
Initialize the value as before.
