ACPI suspend: Fix CONFIG_ACPI_SLEEP dependence and some compilation warnings
Initially CONFIG_PM_SLEEP was defined as CONFIG_SUSPEND || CONFIG_HIBERNATION and some ACPI code, most importantly the code in drivers/acpi/main.c, was written with this assumption. Currently, however, CONFIG_PM_SLEEP is also set when CONFIG_XEN_SAVE_RESTORE is set. This causes some compilation warnings to appear in drivers/acpi/main.c if both CONFIG_SUSPEND and CONFIG_HIBERNATION are unset and CONFIG_PM_SLEEP is set (this was impossible before). To fix this problem, redefine CONFIG_ACPI_SLEEP do depend directly on CONFIG_SUSPEND || CONFIG_HIBERNATION, as originally intended, and use it instead of CONFIG_PM_SLEEP in drivers/acpi/main.c, wherever appropriate. Additionally, move the acpi_target_sleep_state definition from under the #ifdef to prevent compilation from failing in some cases. Signed-off-by: Rafael J.
