V4L/DVB (8088): ivtv: yuv decoder lock fix
write() operations to the yuv device may not always '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 simply moves the existing decoder 'start' sequence to earlier in the write() handler.
