Re: [PATCH v10 6/9] staging: clocking-wizard: Add support for fractional support

Hi Shubhrajyoti,

+static int clk_wzrd_dynamic_reconfig_f(struct clk_hw *hw, unsigned long rate,
+       unsigned long parent_rate)
+{
+ int err;
+ u32 value, pre;
+ unsigned long rate_div, f, clockout0_div;
+ struct clk_wzrd_divider *divider = to_clk_wzrd_divider(hw);
+ void __iomem *div_addr = divider->base + divider->offset;
+
+ rate_div = ((parent_rate * 1000) / rate);

In some cases, the variable seems to overflow.

Thanks,
Zhengxun
