this confuses me. Gerd and i ported this driver from downstream and finally
it's got merged in 4.12.
So do you mean that you backported the mainline version to 4.4 or the
downstream version of 4.4?
On a quick look they seems identical, but they aren't.

I'm very sceptical about this list. The card above is listed as OK and NOK. The
experienced issues doesn't need to be direct related to the card (unproperly
umounted, bad driver, ...).
