From: Daniel Wagner <daniel.wag...@bmw-carit.de>
When running the test script you will get:
kselftest/firmware/fw_userhelper.sh: line 69: echo: write error: Resource
temporarily unavailable
and stops right there. Because the script runs with the '-e' option
which will stop the script at any error.
We should stop there because we are trying to something wrong and get an
error reported back. Instead, ignore the error message and make sure we
do not stop the script by setting the last error code to true.
