[igt-dev] [PATCH i-g-t] tests/kms_cdclk: Minor fix

[Swati Sharma]

Driver still works in a such way that we never reduce CDCLK, but always
only increase it. That was done in order to avoid continuous CDCLK switching,

So, in case if new CDCLK is 307200 and there is no change in CDCLK beacuse
of above stated driver optimization; pass the test else check lt condition.
