Thanks for considering the patch for stable. It seems though that my
notes concerning stable have been lost in transmission.

The first observation is that the regression was introduced in 4.4, so
no earlier stable trees are affected.

Then I had to rebase my patch, because it touches the same lines as
615d23f80efc ("gpio: zynq: Fix the error path"). My initial patch
posting[1] did not consider that patch, so there you go with a rebased
patch that applies to earlier kernel versions. I still use that patch
successfully for bisecting.

I do note however, that the mentioned "Fix the error path" commit also
looks like it should be included into a stable tree, because it fixes an
unbalanced pm_runtime_enable. Thus I recommend applying it to stable as
well. Then the patch that went into 4.7-rc3 just applies.
