[PATCH 4.19 089/243] media: cec: report Vendor ID after initialization

[Greg Kroah-Hartman]

From: Hans Verkuil <hverkuil-cisco@xxxxxxxxx>

[ 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.
