ok, as far as sony-laptop is concerned a dependency on ACPI_EC suffices
to fix the link failure, but I guess that would just hide the real
issue.
IOW: why does ACPI_EC, ACPI_SYSTEM and ACPI_POWER are not set when the
ACPI symbol is?

Given the drivers/acpi/Kconfig portion

  if ACPI
  ...
  config ACPI_EC
          bool
          default y
          help
            ...
  
  config ACPI_POWER
          bool
          default y
  
  config ACPI_SYSTEM
          bool
          default y
          help
	  ...
  ...
  endif

I'd expect the 3 symbols to be all set when CONFIG_ACPI=y.
What am I overseeing?
