From 5c68b7795b4c7bdbd54148c9343b5a5edeb476d7 Mon Sep 17 00:00:00 2001 From: Sergey Shtylyov Date: Thu, 12 Aug 2021 23:39:11 +0300 Subject: [PATCH] i2c: synquacer: fix deferred probing [ Upstream commit 8d744da241b81f4211f4813b0d3c1981326fa9ca ] The driver overrides the error codes returned by platform_get_irq() to -ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the error codes upstream.
