Subject: [PATCH 4.6 68/81] gpio: zynq: Fix the error path

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

------------------

From: Shubhrajyoti Datta <shubhrajyoti.datta@...inx.com>

commit 615d23f80efc60f8c5146223f305d19207c742e4 upstream.

pm_runtime_disable is called only in remove it is missed
out in the error path.
Fix the same.
