Subject: Re: [PATCH] clk: qcom: Don't overwrite 'cfg' in clk_rcg2_dfs_populate_freq()

Quoting Stephen Boyd (2020-01-28 11:33:29)
> The DFS frequency table logic overwrites 'cfg' while detecting the
> parent clk and then later on in clk_rcg2_dfs_populate_freq() we use that
> same variable to figure out the mode of the clk, either MND or not. Add
> a new variable to hold the parent clk bit so that 'cfg' is left
> untouched for use later.
