Sounds good to me.

I agree on this, I think the latest patch set from Rajendra Naik([1]) removes
the EXPORT_SYMBOL for the clk notifier functions.

We will send a patch to dspbridge sources to adopt these changes.
Please let me know your comments.

As an aside, this patch should be reverted. DSPBridge and other drivers
needing clock notifiers should pass function pointers to
clk_notifier_{register,unregister}() in their struct platform_data, rather
than exporting those symbols. This will keep the drivers
platform-agnostic, since system-wide clock notifiers are not yet upstream.
