From 6358d6cb328a772eb6f02c870da61709d539480f Mon Sep 17 00:00:00 2001 From: Sebastien Dugue Date: Thu, 27 Nov 2008 01:19:18 +0000 Subject: [PATCH] powerpc/ibmebus: Get rid of the IRQ mapping in ibmebus_free_irq() ibmebus_free_irq() frees the IRQ but does not remove its mapping, which results in stale entries in the map. This fixes it by adding a call to irq_dispose_mapping() in ibmebus_free_irq().
