From 55764ed37eec48ad1c1cb6784166055e06dcb9df Mon Sep 17 00:00:00 2001 From: York Sun Date: Tue, 9 Aug 2016 14:55:44 -0700 Subject: [PATCH] EDAC, fsl_ddr: Fix IRQ dispose warning when module is removed When compiled as a module, removing it causes kernel warnings when irq_dispose_mapping() is called. Instead of calling irq_of_parse_and_map(), use platform_get_irq() to acquire the IRQ number.
