commit 0ac1b1d7b7424cd6f129b5454b504b3cae746f0e upstream.

The current acpisleep DMI checks only run when CONFIG_SUSPEND is set.
And this may break hibernation on some platforms when CONFIG_SUSPEND
is cleared.

Move acpisleep DMI check into #ifdef CONFIG_ACPI_SLEEP instead.

[rjw: Added acpi_sleep_dmi_check() and rebased on top of earlier
 patches adding entries to acpisleep_dmi_table[].]

commit dbe9a2edd17d843d80faf2b99f20a691c1853418 upstream.

The comparison between the system sleep state being entered
and the lowest system sleep state the given device may wake up
from in acpi_pm_device_sleep_state() is reversed, because the
specification (ACPI 5.0) says that for wakeup to work:

"The sleeping state being entered must be less than or equal to the
 power state declared in element 1 of the _PRW object."

In other words, the state returned by _PRW is the deepest
(lowest-power) system sleep state the device is capable of waking up
the system from.

Moreover, acpi_pm_device_sleep_state() also should check if the
wakeup capability is supported through ACPI, because in principle it
may be done via native PCIe PME, for example, in which case _SxW
should not be evaluated.
