There is a copy and paste bug so we accidentally returned
PTR_ERR(ddata->clk) instead of "ret".

mul_u64_u64_div_u64() returns an u64 that might be bigger than U32_MAX.
To properly handle this case it must not be directly assigned to an u32
value.
Use a wider type for duty and period to make the idiom:
duty = mul_u64_u64_div_u64(...)
if (duty > U32_MAX)
duty = U32_MAX;
actually work as intended.
