From 621ab40df94c00e197bb06d9b853dce9a47139c6 Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Thu, 10 Mar 2016 00:24:49 +0530 Subject: [PATCH] staging: comedi: dt282x: Prefer using macro DIV_ROUND_UP The macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) /(d)). It clarifies the divisor calculations. This was done using the coccinelle script: @@ expression e1; expression e2; @@ ( - ((e1) + e2 - 1) / (e2) + DIV_ROUND_UP(e1,e2) | - ((e1) + (e2 - 1)) / (e2) + DIV_ROUND_UP(e1,e2) ) Signed-off-by: Bhaktipriya Shridhar Signed-off-by: Greg Kroah-Hartman --- drivers/staging/comedi/drivers/dt282x.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/staging/comedi/drivers/dt282x.c b/drivers/staging/comedi/drivers/dt282x.c index 6c26e0924ebd..40bf00984fa5 100644 --- a/drivers/staging/comedi/drivers/dt282x.c +++ b/drivers/staging/comedi/drivers/dt282x.c @@ -377,7 +377,7 @@ static unsigned int dt282x_ns_to_timer(unsigned int *ns, unsigned int flags) divider = (*ns) / base; break; case CMDF_ROUND_UP: - divider = (*ns + base - 1) / base; + divider = DIV_ROUND_UP(*ns, base); break; } if (divider < 256) { -- 2.39.5
