ACPI: sleep: init_set_sci_en_on_resume for Dell Studio 155x
ACPI: fix acpi_hest_firmware_first_pci() caused oops
sbshc: acpi_device_class "smbus_host_controller" too long
power_meter: acpi_device_class "power_meter_resource" too long
acpi_pad: "processor_aggregator" name too long
PNP: don't check for conflicts with bridge windows
ACPI: DMI init_set_sci_en_on_resume for multiple Lenovo ThinkPads
PNPACPI: compute Address Space length rather than using _LEN
ACPI: silence kmemcheck false positive
