Subject: [PATCH] Bluetooth: log advertisement packet length if it gets corrected
Git-commit: 943d5d92c5e87aa8293aae6de2b3ee977aa7d3cf
Patch-mainline: v5.8-rc1
References: jsc#SLE-13430
The error could indicate a problem with the Bluetooth device. It
is easier to investigate if the packet's actual length gets logged,
not just the fact that a discrepancy occurred.
