this is not a valid argument against this patch. The patch does not reduce the specified minimum delays, it only reduces the maximum delays.
If the minimum delays are not actually correct your drivers is already buggy since the kernel already does not guarantee that you get more than the minimum,
depending on what else is going on you are getting something arbitrary between minimum and maxium.
this patch moves the maximum closer to the minimum reducing variability
