Subject: [PATCH 3.16 003/132] media: ivtv: update *pos correctly in
 ivtv_read_pos()

3.16.74-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit f8e579f3ca0973daef263f513da5edff520a6c0d upstream.

We had intended to update *pos, but the current code is a no-op.

Fixes: 1a0adaf37c30 ("V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder")
