Subject: [PATCH 14/20] staging: vchiq_core: reduce indention in release_service_messages
Date: Sat, 15 May 2021 21:10:53 +0200 [thread overview]
Message-ID: <1621105859-30215-15-git-send-email-stefan.wahren@i2se.com> (raw)
In-Reply-To: <1621105859-30215-1-git-send-email-stefan.wahren@i2se.com>
It's possible to convert the if statement into a continue early and
save an indention level.
