From 35386dfd13b746daf36a393bdf066dbe9b9b7aed Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 3 Sep 2018 19:33:23 +0200 Subject: 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.
