[PATCH 4.2.y-ckt 047/218] aic7xxx: Fix queue depth handling

From: Kamal Mostafa
Date: Thu Mar 31 2016 - 17:15:52 EST

4.2.8-ckt7 -stable review patch. If anyone has any objections, please let me know.


From: Alan <gnomes@xxxxxxxxxxxxxxxxxxx>

commit 5a51a7abca133860a6f4429655a9eda3c4afde32 upstream.

We were setting the queue depth correctly, then setting it back to
two. If you hit this as a bisection point then please send me an email
as it would imply we've been hiding other bugs with this one.
