SubjectApplied "spi: spidev_test: Improve decoded text part of hex dump" to the spi tree
The patch

spi: spidev_test: Improve decoded text part of hex dump

has been applied to the spi tree at

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Subject: [PATCH] spi: spidev_test: Improve decoded text part of hex dump

- Print spaces as spaces,
- Do not print characters > 126, as they will be shown as garbage
in the modern UTF-8 era,
- Use a normal period instead of its hexadecimal ASCII value,
- Delimit the text part with pipe symbols on both sides (was left side
only), without any spaces, to make it clear where the decoded text
starts and ends,
- Drop a useless comment.
