Subject: [PATCH] microblaze: intc: set the default irq_domain
Date: Sun, 17 Mar 2013 04:48:56 -0500	[thread overview]
Message-ID: <51459188.7000104@opello.org> (raw)

Register the irq_domain created during initialization as the default so
that device drivers can pass NULL to irq_create_mapping and get a
virtual irq to pass to request_irq.
