[PATCH] cpufreq: mediatek: fix build error
From: Arnd Bergmann <arnd@arndb.de>
Date: 2015-11-16 21:28:26
The recently added mt8173 cpufreq driver relies on the cpu topology that is always present on ARM64 but optional on ARM32: drivers/cpufreq/mt8173-cpufreq.c: In function 'mtk_cpufreq_init': drivers/cpufreq/mt8173-cpufreq.c:441:30: error: 'cpu_topology' undeclared (first use in this function) cpumask_copy(policy->cpus, &cpu_topology[policy->cpu].core_sibling); This refines the Kconfig dependencies so that we can still build on ARM32, but only if COMPILE_TEST is selected and the CPU topology code is present.
