Subject: [PATCH AUTOSEL 4.14 138/371] media: cx18: update *pos correctly in cx18_read_pos()

In-Reply-To: <20200116172403.18149-1-sashal@kernel.org>

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

[ Upstream commit 7afb0df554292dca7568446f619965fb8153085d ]

We should be updating *pos.  The current code is a no-op.
