Subject: [PATCH 4.14 058/267] media: cec: report Vendor ID after initialization

From: Hans Verkuil <hverkuil-cisco@...all.nl>

[ Upstream commit 7f02ac77c768ba2bcdd0ce719c1fca0870ffe2fb ]

The CEC specification requires that the Vendor ID (if any) is reported
after a logical address was claimed.

This was never done, so add support for this.
