From 097a48597f554fece7eff6e6d16471fe5e4be9eb Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 21 Jun 2008 13:09:46 +0200 Subject: ivtv: yuv decoder lock fix (2) From: Ian Armstrong The IVTV_IOC_DMA_FRAME ioctl fails to correctly 'start' the decoder. Although yuv output will be correct, some functions which should be disabled while the decoder is in use remain enabled. This can result in hardware registers being corrupted, causing problems with the mpeg decoder. This patch ensures the decoder 'start' sequence is called, disabling these functions until the device is closed.
