From 8552befa3086589876032d5e1ce5797ae2bb684b Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 2 Oct 2014 22:25:22 -0300 Subject: [PATCH] iio: adc: vf610: Propagate the real error when platform_get_irq() fails There is no need to pass a 'fake' return value when platform_get_irq() fails. Propagate the real error instead. While at it, only consider negative numbers returned by platform_get_irq() as error.
