Subject: [PATCH] clk: iproc: round clock rate to the closest
Git-commit: 9f7d5042a64160e20c73d734f9ed5dd8c6bba205
Patch-mainline: v5.9-rc1
References: bsc#1111666

Change from 'DIV_ROUND_UP' to 'DIV_ROUND_CLOSEST' when calculating the
clock divisor in the iProc ASIU clock driver to allow to get to the
closest clock rate.

Fixes: 5fe225c105fd ("clk: iproc: add initial common clock support")
