On the other hand, ghes_init() relies on sdei_init() to detect the SDEI version and (un)register events. The dependencies are as follows: ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init() ghes_init() => sdei_init() HEST is not PCI-specific and initcall ordering is implicit and not well-defined within a level. Based on above, remove acpi_hest_init() from acpi_pci_root_init() and convert ghes_init() and sdei_init() from initcalls to explicit calls in the following order: acpi_hest_init() ghes_init() sdei_init() Signed-off-by: Shuai Xue Signed-off-by: Rafael J.
