Compiler is not happy about a couple of symbols that, it thinks,
are not declared:

  warning: symbol 'acpi_device_lock' was not declared. Should it be static?
  warning: symbol 'acpi_wakeup_device_list' was not declared. Should it be static?

Include "sleep.h" to have them explicitly declared and make
the compiler happy.

I've just applied a patch from Ben Dooks making the exact same change.
