Subject: [PATCH 07/18] ALSA: dummy: Use DIV_ROUND_UP() instead of open-coding it
Date: Wed, 23 Dec 2020 18:22:18 +0100 [thread overview]
Message-ID: <20201223172229.781-7-lars@metafoo.de> (raw)
In-Reply-To: <20201223172229.781-1-lars@metafoo.de>
Use DIV_ROUND_UP() instead of open-coding it. This documents intent
and makes it more clear what is going on for the casual reviewer.
Generated using the following the Coccinelle semantic patch.
// <smpl>
@@
expression x, y;
@@
-(((x) + (y) - 1) / (y))
+DIV_ROUND_UP(x, y)
// </smpl>
