Subject: [PATCH] media: cec: report Vendor ID after initialization

Git-commit: 7f02ac77c768ba2bcdd0ce719c1fca0870ffe2fb

Patch-mainline: v5.0-rc1

References: bsc#1051510

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.
