(for future reference - a simple build fix like this is probably fine to commit without precommit review/without a pull request - but generally if you make a pull request you should wait until it's reviewed (creating a pull request amounts to saying "I'm not confident in this change and want a second set of eyes before I commit it" - so then committing it without that review seems problematic). If you only wanted to create the pull request to run automated presubmit checks, please create the PR with the skip-precommit-approval to indicate that)
