Revision 46cb52ad414ac829680d0bb8cc7090ac2b577ca7 authored by Linus Walleij on 15 July 2018, 20:09:29 UTC, committed by Jens Axboe on 27 August 2018, 20:25:54 UTC 
ata: ftide010: Add a quirk for SQ201
 
The DMA is broken on this specific device for some unknown
reason (probably badly designed or plain broken interface
electronics) and will only work with PIO. Other users of
the same hardware does not have this problem.

Add a specific quirk so that this Gemini device gets
DMA turned off. Also fix up some code around passing the
port information around in probe while we're at it.
