This is fine but devm_clk_get() is only in Russell's tree so it'll need
to wait for after the merge window - can you please resend then?

devm_clk_get() is in linux-next. Isn't this ok?

No. If I apply it to for-3.5 then for-3.5 won't build. It needs to be
merged into the branch where the patch gets applied.
