In the Linux kernel, the following vulnerability has been resolved:
ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate()
The psc->div[] array has psc->num_div elements. These values come from
when we call clk_hw_register_div(). It's adc_divisors and
ARRAY_SIZE(adc_divisors)) and so on. So this condition needs to be >=
instead of > to prevent an out of bounds read.
