6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Matthieu Baerts (NGI0)" matttbe@kernel.org
commit 76a2d8394cc183df872adf04bf636eaf42746449 upstream.
The checksum and fail counters might not be available. Then no need to display an extra message with missing info.
While at it, fix the indentation around, which is wrong since the same commit.
