Subject: [PATCH 6/8] auto: promote DIV_U64_ROUND_CLOSEST macro to function
Date: Thu, 18 May 2023 18:46:47 +0300 [thread overview]
Message-ID: <20230518154648.581643-6-adobriyan@gmail.com> (raw)
In-Reply-To: <20230518154648.581643-1-adobriyan@gmail.com>
Both arguments are cast to specific types, so moving cast earlier is OK.
