[PATCH] cpufreq: airoha: add CONFIG_OF dependency

From: Arnd Bergmann
Date: Wed Jan 22 2025 - 01:55:28 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

Compile-testing without CONFIG_OF leads to a harmless build warning:

drivers/cpufreq/airoha-cpufreq.c:109:34: error: 'airoha_cpufreq_match_list' defined but not used [-Werror=unused-const-variable=]
109 | static const struct of_device_id airoha_cpufreq_match_list[] __initconst = {
| ^~~~~~~~~~~~~~~~~~~~~~~~~

It would be possible to mark the variable as __maybe_unused to shut up
that warning, but a Kconfig dependency seems more appropriate as this still
allows build testing in allmodconfig and randconfig builds on all
architectures.

Fixes: 84cf9e541ccc ("cpufreq: airoha: Add EN7581 CPUFreq SMCCC driver")
