From 6f1e120438144a47463b80c3e113334a6bd0e77c Mon Sep 17 00:00:00 2001 From: Guillaume Clement Date: Sat, 10 Aug 2013 09:06:04 +0200 Subject: [PATCH] gma500: Fix SDVO turning off randomly Some Poulsbo cards seem to incorrectly report SDVO_CMD_STATUS_TARGET_NOT_SPECIFIED instead of SDVO_CMD_STATUS_PENDING, which causes the display to be turned off.
