Subject: ALSA: riptide: Use DIV_ROUND_UP
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=cf7d7edc7a120fd5001f6dcc1e9f2c8e9c09e6c9;p=deliverable%2Flinux.git

ALSA: riptide: Use DIV_ROUND_UP

The kernel.h macro DIV_ROUND_UP performs the computation
(((n) + (d) - 1) /(d)) but is perhaps more readable.

The Coccinelle script used to make this change is as follows:
@haskernel@
@@

#include <linux/kernel.h>

@depends on haskernel@
expression n,d;
@@

(
- (n + d - 1) / d
+ DIV_ROUND_UP(n,d)
|
- (n + (d - 1)) / d
+ DIV_ROUND_UP(n,d)
)
