Subject: [PATCH v3 3/5] bug: Assign values once in bug_get_file_line()
Date: Thu, 18 Mar 2021 14:33:09 +0000	[thread overview]
Message-ID: <20210318143311.839894-4-ascull@google.com> (raw)
In-Reply-To: <20210318143311.839894-1-ascull@google.com>

Set bug_get_file_line()'s output parameter values directly rather than
first nullifying them and then conditionally setting new values.
