Subject: thermal: intel_pch_thermal: fix build for ACPI not enabled
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=be133722df5168d2f304cc59b80d3d21d6ea9433;p=linux.git

thermal: intel_pch_thermal: fix build for ACPI not enabled

The reference to acpi_gbl_FADT causes a build error when ACPI is not
enabled. Fix by making that conditional on CONFIG_ACPI.

../drivers/thermal/intel/intel_pch_thermal.c: In function 'pch_wpt_suspend':
../drivers/thermal/intel/intel_pch_thermal.c:217:8: error: 'acpi_gbl_FADT' undeclared (first use in this function); did you mean 'acpi_get_type'?
  if (!(acpi_gbl_FADT.flags & ACPI_FADT_LOW_POWER_S0))
        ^~~~~~~~~~~~~
