From 40af583d16465aae2a570e469fc72a5d24438a20 Mon Sep 17 00:00:00 2001 From: Martin Kaiser Date: Sun, 1 Nov 2020 18:18:06 +0100 Subject: [PATCH] i2c: exynos5: fix platform_get_irq error handling If platform_get_irq returns an error, relay this error to the caller of the probe function. Don't change all errors to -EINVAL. This breaks the case where platform_get_irq returns -EPROBE_DEFER.
