Subject: [PATCH] ata: acpi: Remove ata_dev_acpi_handle stub in libata.h

The ata_dev_acpi_handle is defined in libata-acpi.c and the only
external user is libata-zpodd.c, which is built when CONFIG_ATA_ACPI
is set, so there is no need to make an empty stub function for
!CONFIG_ATA_ACPI case in libata.h. It also causes compile errors due to
acpi_handle is not defined when !CONFIG_ACPI. This patch fixes this
problem by removing the empty stub.

Yeap, tested and works.  Applied to libata/for-3.12.  Thanks.

Stephen, sorry about the trouble.
