Subject: [PATCH] ACPI: arm64: export acpi_arch_thermal_cpufreq_pctg

From: Arnd Bergmann <[email protected]>

The cpufreq code can be in a loadable module, so the architecture support
for it has to be exported:

ERROR: modpost: "acpi_arch_thermal_cpufreq_pctg" [drivers/acpi/processor.ko] undefined!

Fixes: 310293a2b941 ("ACPI: processor: reduce CPUFREQ thermal reduction pctg for Tegra241")
