Subject: [PATCH] cpufreq: dbx500: add a Kconfig symbol
Date: Thu, 11 May 2017 14:12:29 +0200 [thread overview]
Message-ID: <20170511121258.3521041-1-arnd@arndb.de> (raw)
Moving the cooling code into the cpufreq driver caused a possible build failure
when the cpu_thermal helper code is a loadable module or disabled:
drivers/cpufreq/dbx500-cpufreq.o: In function `dbx500_cpufreq_ready':
dbx500-cpufreq.c:(.text.dbx500_cpufreq_ready+0x4): undefined reference to `cpufreq_cooling_register'
This adds the same dependency that we have in other cpufreq drivers,
forcing the driver to be disabled when we can't possibly link it.
Fixes: 19678ffb9fd6 ("cpufreq: dbx500: Manage cooling device from cpufreq driver")
