Subject: selftests/ftrace: Replace echo -e with printf
X-Git-Tag: v5.1-rc1~95^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=37fb665b059edcd6ab87b1541402eef3dac91168;p=thirdparty%2Fkernel%2Flinux.git

selftests/ftrace: Replace echo -e with printf

echo -e is not POSIX. Depending on what /bin/sh is, we can get
incorrect output like:
$ -e -n [1] Basic trace file check
$ -e 	[PASS]

Fix that by using printf instead.
