From ecf305cf81c68446508c283015694e304939be5f Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Fri, 1 Feb 2013 20:37:06 -0600 Subject: [PATCH] omap: mailbox: call request_irq after mbox queues are allocated The OMAP mailbox startup code is enabling the interrupt before any of the associated mailbox queues are allocated. Move this code so that the interrupt configuration for a mailbox is together.
