From d509a83cea8a64478c7899f28e961543b6569cfc Mon Sep 17 00:00:00 2001 From: Alex Smith Date: Fri, 24 Jul 2015 17:24:26 +0100 Subject: [PATCH] dmaengine: jz4780: Don't use devm_*_irq() functions We must explicitly free the IRQ before the device is unregistered in case any device interrupt still occurs, so there's no point in using the managed variations of the IRQ functions. Change to the regular versions.
