Hi, Len. We are just using the data that is valid and ignoring the invalid ones. The benefit is that we will have frequency control working on Linux even if the table is not 100% correct. We are not guessing anything, from what I see. This is not specific to a brand or manufacturer. The test for the entry was there all along, so the workaround is just improving on the simple case (bail out completely and lose the capability). With this patch, my battery lasts around 4h. Without it, less then 1h.
