Subject: [PATCH 022/114] clk: ingenic: cgu: convert from round_rate() to
 determine_rate()

From: Brian Masney <bmasney@...hat.com>

The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
on the cover letter of this series.
