#1375755 — [PATCH 3/5] cpufreq: Loongson1: Use dev_get_platdata() to get platform_data

From: Kelvin Cheung <keguang.zhang@gmail.com>

This patch uses dev_get_platdata() to get the platform_data
instead of referencing it directly.

Actually you should fold above into the first patch of the series,
that renames this file. It makes much sense that way.

You added a '{' here, but the closing '}' is added way down..
Something is wrong here I feel..

Why do this change at all? Do it in the first patch if you really want
to.
