From c75b505ddaa08098940441226bb3a87c5b3179c0 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Tue, 8 Oct 2013 10:56:11 +0200 Subject: [PATCH] cpufreq: Add dummy cpufreq_cpu_get/put for CONFIG_CPU_FREQ=n The drm/i915 driver wants to adjust it's own power policies using the cpu policies as a guideline (we can implicitly boost the cpus through the gpus on some platforms). To avoid a dreaded select (since a depends will leave users wondering where where their driver has gone too) add dummy functions. Reported-by: kbuild test robot Cc: kbuild test robot Cc: "Rafael J.
