[PATCH] ACPI / tables: Add an ifdef around amlcode and dsdt_amlcode

From: Nathan Chancellor
Date: Thu Dec 20 2018 - 14:40:16 EST


Clang warns:

drivers/acpi/tables.c:715:14: warning: unused variable 'amlcode'
[-Wunused-variable]
static void *amlcode __attribute__ ((weakref("AmlCode")));
^
drivers/acpi/tables.c:716:14: warning: unused variable 'dsdt_amlcode'
[-Wunused-variable]
static void *dsdt_amlcode __attribute__ ((weakref("dsdt_aml_code")));
^
2 warnings generated.

The only uses of these variables are hiddem behind CONFIG_ACPI_CUSTOM_DSDT
so do the same thing here.

Fixes: 82e4eb4e9653 ("ACPI / tables: add DSDT AmlCode new declaration name support")
