CVE-2022-49189
clk: qcom: clk-rcg2: Update logic to calculate D value for RCG
In the Linux kernel, the following vulnerability has been resolved:
clk: qcom: clk-rcg2: Update logic to calculate D value for RCG
The display pixel clock has a requirement on certain newer platforms to
support M/N as (2/3) and the final D value calculated results in
underflow errors.
As the current implementation does not check for D value is within
the accepted range for a given M & N value. Update the logic to
calculate the final D value based on the range.
