Subject: [PATCH 4.1 27/95] ARM: tegra: paz00: use con_ids to refer GPIOs in gpiod_lookup table

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

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

From: Dmitry Osipenko <digetx@...il.com>

commit e77b675f8786f38d40fc1562e1275875daf67fef upstream.

Commit 72daceb9a10a ("net: rfkill: gpio: Add default GPIO driver mappings
for ACPI") removed possibility to request GPIO by table index for non-ACPI
platforms without changing its users. As result "shutdown" GPIO request
will fail if request for "reset" GPIO succeeded or "reset" will be
requested instead of "shutdown" if "reset" wasn't defined. Fix it by
making gpiod_lookup_table use con_id's instead of indexes.
