commit: https://git.buildroot.net/buildroot/commit/?id=22bb9b2c28a6835e8414cd0cd6cbb61223c0f0d4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

In order to check if the initial database needs created, the startup
script calls ls -1 $MYSQL_LIB | wc -l to check the number of files in
the directory. If the directory does not exist, an error is printed.
We fix this by redirecting stderr to /dev/null for the ls call.
