From b494b48dacb4dd848d76bc8871e55716486f0253 Mon Sep 17 00:00:00 2001 From: Sudeep KarkadaNagesha Date: Tue, 10 Sep 2013 18:59:47 +0100 Subject: cpufreq: imx6q-cpufreq: assign cpu_dev correctly to cpu0 device Commit cdc58d602d2e657602a90c190cbf745886c95977 "cpufreq: imx6q-cpufreq: remove device tree parsing for cpu nodes" assumed the pdev->dev is set to cpu0 device in the platform code. But it actually points to the virtual cpufreq-cpu0 platform device which is not present in the device tree. Most of the information needed by cpufreq is stored in cpu0 DT node. So cpu_dev must point to cpu0 device. This patch fixes the wrong assignment to cpu_dev.
