linux-next: build warning after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (powerpc
allyesconfig) produced this warning:

drivers/net/ethernet/apm/xgene/xgene_enet_hw.c: In function 'xgene_enet_phy_connect':
drivers/net/ethernet/apm/xgene/xgene_enet_hw.c:759:22: warning: unused variable 'adev' [-Wunused-variable]
  struct acpi_device *adev;
                      ^

Introduced by commit

  8089a96f601b ("drivers: net: xgene: Add backward compatibility")
(CONFIG_ACPI si not set for tis build)
