4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Geert Uytterhoeven geert+renesas@glider.be
commit d63c16f8e1ab761775275adcf54f4bef7c330295 upstream.
Printk format "%pCr" will be removed soon, as clk_get_rate() must not be called in atomic context.
Replace it by open-coding the operation. This is safe here, as the code runs in task context.
