[PATCH 02/18] ALSA: aloop: Use DIV_ROUND_UP() instead of open-coding it

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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>
