We had ignore lines for these warnings, but it turns out this is most likely a bug in shellcheck and we can work around it by moving the helper function definition before any of the functions that use the helper function. Hopefully it'll be fixed soon. Ref: https://github.com/koalaman/shellcheck/issues/2873 Signed-off-by: Aleksa Sarai <cyphar@cyphar.com>
