From a692838dcaacb5f6f05fac73abb99d92dd7b1021 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 2 Aug 2009 10:46:45 +0200 Subject: [PATCH] arch/arm/plat-iop: Use DIV_ROUND_CLOSEST The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d but is perhaps more readable. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @haskernel@ @@ #include @depends on haskernel@ expression x,__divisor; @@ - (((x) + ((__divisor) / 2)) / (__divisor)) + DIV_ROUND_CLOSEST(x,__divisor) // Signed-off-by: Julia Lawall Signed-off-by: Dan Williams --- arch/arm/plat-iop/time.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm/plat-iop/time.c b/arch/arm/plat-iop/time.c index 3695bbe..8da95d5 100644 --- a/arch/arm/plat-iop/time.c +++ b/arch/arm/plat-iop/time.c @@ -85,7 +85,7 @@ void __init iop_init_time(unsigned long tick_rate) { u32 timer_ctl; - ticks_per_jiffy = (tick_rate + HZ/2) / HZ; + ticks_per_jiffy = DIV_ROUND_CLOSEST(tick_rate, HZ); ticks_per_usec = tick_rate / 1000000; next_jiffy_time = 0xffffffff; iop_tick_rate = tick_rate; -- 1.8.2.3
