    clk: sunxi: Fix M factor computation for APB1 · ac95330b
    Stéphan Rafin authored
    commit cfa63688 ("clk: sunxi: factors: Consolidate get_factors
    parameters into a struct") introduced a regression for m factor
    computation in sun4i_get_apb1_factors function.
    
    The old code reassigned the "parent_rate" parameter to the targeted
    divisor value and was buggy for the returned frequency but not for the
    computed factors. Now, returned frequency is good but m factor is
    incorrectly computed (its max value 31 is always set resulting in a
    significantly slower frequency than the requested one...)
    
    This patch simply restores the original proper computation for m while
    keeping the good changes for returned rate.
