From 3eaead579ebc09d4f4c050c9b6ce6d67337bcb20 Mon Sep 17 00:00:00 2001 From: Wu Fengguang Date: Fri, 14 May 2010 16:36:15 +0800 Subject: [PATCH] ALSA: hdmi - dont fail on extra nodes The number of HDMI nodes is expected to go up in future. So don't fail hard on seeing extra converter/pin nodes. We can still operate safely on the nodes within MAX_HDMI_CVTS/MAX_HDMI_PINS.
