[ 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.
