From 50dc60a25597e10a731c8a0813cb3e88db345f54 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 1 Jul 2016 17:45:57 +0200 Subject: [PATCH] dmaengine: axi-dmac: Propagate errors from platform_get_irq() Propagate errors returned by platform_get_irq() to the driver core. This will enable proper probe deferring for the driver in case the IRQ provider has not been registered yet.
