+Subject: kselftest: Add a ksft_perror() helper
+
+From: Mark Brown <broonie@kernel.org>
+
+commit 907f33028871fa7c9a3db1efd467b78ef82cce20 upstream.
+
+The standard library perror() function provides a convenient way to print
+an error message based on the current errno but this doesn't play nicely
+with KTAP output. Provide a helper which does an equivalent thing in a KTAP
+compatible format.
+
+nolibc doesn't have a strerror() and adding the table of strings required
+doesn't seem like a good fit for what it's trying to do so when we're using
+that only print the errno.
