From d80d499ed926e70b429d309360f5910d5ad54788 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 2 Mar 2011 15:53:07 +0200 Subject: OMAP: DSS2: DSI: fix IRQ debug prints print_irq_status functions can be called with empty irq status when full irq debugging is enabled. This patch makes print_irq_status functions return immediately when given an empty irq status to lessen the debug spam slightly.
