[PATCH 107/141] V4L/DVB (3375): Add AUDIO_GET_PTS and VIDEO_GET_PTS ioctls

[mchehab@infradead.org]

From: Andreas Oberritter <obi@linuxtv.org>
Date: 1141009740 -0300

Add two new ioctls to read the 33 bit presentation time stamp from audio
and video devices as defined in ITU T-REC-H.222.0 and ISO/IEC 13818-1.
