Subject: clk: mvebu: corediv: convert from round_rate() to determine_rate()
X-Git-Tag: v6.18-rc1~50^2^2~2^2~32
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9a649ab1cf64c9709b43cdfdc37e2ba2f200f5d0;p=thirdparty%2Fkernel%2Flinux.git

clk: mvebu: corediv: convert from round_rate() to determine_rate()

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.
