Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (KCONFIG_NAME)
failed like this:

drivers/net/ethernet/apm/xgene/xgene_enet_main.c: In function 'xgene_get_port_id_acpi':
drivers/net/ethernet/apm/xgene/xgene_enet_main.c:880:2: error: implicit declaration of function 'acpi_evaluate_integer' [-Werror=implicit-function-declaration]
  status = acpi_evaluate_integer(ACPI_HANDLE(dev), "_SUN", NULL, &temp);
  ^
drivers/net/ethernet/apm/xgene/xgene_enet_main.c: At top level:
drivers/net/ethernet/apm/xgene/xgene_enet_main.c:874:12: warning: 'xgene_get_port_id_acpi' defined but not used [-Wunused-function]
 static int xgene_get_port_id_acpi(struct device *dev,
            ^

Caused by commit 0738c54d6324 ("drivers: net: xgene: Fix the ACPI support
for RGMII/SGMII0/XFI interface of APM X-Gene SoC ethernet controller").

I have applied this patch for today:
