FS#1242 - SATA broken on kernel 4.9 on mt7621
User who did this - neheb (neheb)

----------
I got rid of a bunch of CONFIG settings out of confg-4.9 but after observing the actual generated .config file in the build directory, there's no difference. So it seems this is a dead-end...

In other news, I seem not to have these issues anymore. I don't know why. The only answer I have is that it was fixed upstream. I can't see what would have done that though... I have working firmware from 4.9.75. I need to do more testing, but this seems to be gone.

Even if placebo, try this patch. It may work, may not...
