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.
