Subject[PATCH 4.14 144/343] media: ivtv: update *pos correctly in ivtv_read_pos()
Date
From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit f8e579f3ca0973daef263f513da5edff520a6c0d ]

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")
