Any idea if this patch if good to go in mainline? I am facing the same
issue on Tegra with 3.1.5 and this patch fixes the issue caused by [1].
Ideally if this change is ok, then it should be merged into 3.1.6 too.
Since this change seems to fix the issue at hand, I intend to merge the
change directly in our internal repo and wait for it to be a part of 3.1.6.

Thanks.
