Hmm, this looks like it could do with improvement, especially as we're
moving everything over to a common clk API.

1. This driver could do with clk_prepare()/clk_unprepare() calls.
2. This driver should not be making the assumption that NULL means
   it can avoid clk_* calls.  It should instead be using
	if (!IS_ERR(clk))

Thanks.
