   4 Subject: serial: sh-sci: Stop using printk format %pCr
   5

   8 commit d63c16f8e1ab761775275adcf54f4bef7c330295 upstream.
   9
  10 Printk format "%pCr" will be removed soon, as clk_get_rate() must not be
  11 called in atomic context.
  12
  13 Replace it by open-coding the operation.  This is safe here, as the code
  14 runs in task context.
