Subject: [PATCH] Bluetooth: btintel: Collect tlv based active firmware build info in FW mode
Git-commit: 88981354730ce118a76aa030d19fd1308cd2007b
Patch-mainline: v5.13-rc1
References: bsc#1188893
In Operational firmware mode, 'Minimum FW version' TLV ID is not available.
So, we cannot fetch already running firmware info for comparison against
another build. However, It can be collected using a combination of other
TLV ID's information.
