Subject: [PATCH 1/4] clk: renesas: cpg-mssr: Stop using printk format %pCr
Date: Fri,  1 Jun 2018 11:28:19 +0200	[thread overview]
Message-ID: <1527845302-12159-2-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1527845302-12159-1-git-send-email-geert+renesas@glider.be>

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.
