Subject: [PATCH 110/114] clk: visconti: pll: 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.
