[PATCH 3.13 110/162] iio: mxs-lradc: Propagate the real error code on platform_get_irq() failure

[Kamal Mostafa]

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

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

From: Fabio Estevam <fabio.estevam at freescale.com>

commit 9610e08e97370ca7780bea977b03355fa0261635 upstream.

No need to return a 'fake' return value on platform_get_irq() failure.

Just return the error code itself instead.
