Subject: [PATCH 4.9 015/101] clk: renesas: cpg-mssr: Stop using printk format %pCr

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <geert+renesas@...der.be>

commit ef4b0be62641d296cf4c0ad8f75ab83ab066ed51 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.
