Zichen Xie 00f8f70a0e clk: sophgo: avoid integer overflow in sg2042_pll_recalc_rate() ... This was found by a static analyzer. There may be a potential integer overflow issue in sg2042_pll_recalc_rate(). numerator is defined as u64 while parent_rate is defined as unsigned long and ctrl_table.fbdiv is defined as unsigned int. On 32-bit machine, the result of the calculation will be limited to "u32" without correct casting. Integer overflow may occur on high-performance systems.
