Subject: [PATCH] powerpc/ibmebus: Get rid of the IRQ mapping in ibmebus_free_irq()
Date: Thu, 27 Nov 2008 12:19:18 +0100 [thread overview]
Message-ID: <20081127121918.2cfa881e@bull.net> (raw)
ibmebus_free_irq() frees the IRQ but does not remove its mapping which
results in stale entries in the map.
Fix this by adding a call to irq_dispose_mapping() in ibmebus_free_irq().
