Subject: [PATCH 3.16.y-ckt 059/135] pinctrl: lantiq: remove bogus of_gpio_chip_add

3.16.7-ckt6 -stable review patch.  If anyone has any objections, please let me know.

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

From: Johan Hovold <johan@...nel.org>

commit 41f632fe177bc4822c2e8236fe7c291e6e9eb6f8 upstream.

Remove bogus call to of_gpiochip_add (and of_gpio_chip remove in error
path) which is also called when adding the gpio chip.

This prevents adding the same pinctrl range twice.

Fixes: 3f8c50c9b110 ("OF: pinctrl: MIPS: lantiq: implement lantiq/xway
pinctrl support")
