3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Zhang Rui <rui.zh...@intel.com> 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[].] References: https://bugzilla.kernel.org/show_bug.cgi?id=45921 Signed-off-by: Zhang Rui <rui.zh...@intel.com> Signed-off-by: Rafael J.
