6.18-stable review patch.  If anyone has any objections, please let me know.

From: Brian Masney <bmasney@redhat.com>

[ Upstream commit 463b97bef0c9fb02b743d6b9f0d698cae81a1d9f ]

The divider_round_rate() function is now deprecated, so let's migrate
to divider_determine_rate() instead so that this deprecated API can be
removed.

Note that when the main function itself was migrated to use
determine_rate, this was mistakenly converted to:

    req->rate = divider_round_rate(...)

This is invalid in the case when an error occurs since it can set the
rate to a negative value.

Fixes: 64613d7fb42f ("clk: bm1880: convert from round_rate() to determine_rate()")
