Hi Jeff, After merging the libata tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/ata/libata-acpi.c: In function 'ata_acpi_set_state': drivers/ata/libata-acpi.c:872:5: error: too few arguments to function 'acpi_pm_device_sleep_state' include/acpi/acpi_bus.h:418:5: note: declared here Caused by commit 3bd46600a7a7 ("libata-acpi: add ata port runtime D3Cold support") from the libata tree interacting with commit ee85f543710d ("ACPI/PM: specify lowest allowed state for device sleep state") from the pci tree. I added the following merge fix patch (and can carry it as necessary): From: Stephen Rothwell Date: Mon, 2 Jul 2012 12:07:25 +1000 Subject: [PATCH] libata-acpi: fix up for acpi_pm_device_sleep_state API change Signed-off-by: Stephen Rothwell --- drivers/ata/libata-acpi.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/ata/libata-acpi.c b/drivers/ata/libata-acpi.c index 4112eaa..a2b16c9 100644 --- a/drivers/ata/libata-acpi.c +++ b/drivers/ata/libata-acpi.c @@ -869,7 +869,7 @@ void ata_acpi_set_state(struct ata_port *ap, pm_message_t state) if (state.event != PM_EVENT_ON) { acpi_state = acpi_pm_device_sleep_state( - &dev->sdev->sdev_gendev, NULL); + &dev->sdev->sdev_gendev, NULL, ACPI_STATE_D3); if (acpi_state > 0) acpi_bus_set_power(handle, acpi_state); /* TBD: need to check if it's runtime pm request */ -- 1.7.10.280.gaa39 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
