Subject: [PATCH 4.19 20/74] ACPI: blacklist: fix clang warning for unused DMI table

[ Upstream commit b80d6a42bdc97bdb6139107d6034222e9843c6e2 ]

When CONFIG_DMI is disabled, we only have a tentative declaration,
which causes a warning from clang:

drivers/acpi/blacklist.c:20:35: error: tentative array definition assumed to have one element [-Werror]
static const struct dmi_system_id acpi_rev_dmi_table[] __initconst;

As the variable is not actually used here, hide it entirely
in an #ifdef to shut up the warning.
