A DVB demultiplexer device can be used to set up either a PES filter or a section filter. In the former case, the ts field of the feed union of struct dmxdev_filter is used, in the latter case the sec field of the same union is used. The ts field is a struct list_head, and is currently initialized in the open() method of the demux device. When for a given demuxer a section filter is set up, the sec field is played with, thus if a PES filter needs to be set up after that the ts field will be corrupted, causing a kernel oops. This fix moves the list head initialization to dvb_dmxdev_pes_filter_set(), so that the ts field is properly initialized every time a PES filter is set up.
