Subject: cpufreq: pmac32-cpufreq: remove device tree parsing for cpu nodes
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1037b2752345cc5666e90b711a913ab2ae6c5920;p=deliverable%2Flinux.git

cpufreq: pmac32-cpufreq: remove device tree parsing for cpu nodes

Now that the cpu device registration initialises the of_node(if available)
appropriately for all the cpus, parsing here is redundant.

This patch removes DT parsing and uses cpu->of_node instead.
