From 75b697f747b14b0c6afae48ee0f5e605abd2df4c Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 1 Aug 2009 16:48:41 -0300 Subject: V4L/DVB (12483): 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@ @@ @depends on haskernel@ expression x,__divisor; @@ - (((x) + ((__divisor) / 2)) / (__divisor)) + DIV_ROUND_CLOSEST(x,__divisor) // Signed-off-by: Julia Lawall Signed-off-by: Mauro Carvalho Chehab --- drivers/media/dvb/pluto2/pluto2.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media/dvb/pluto2') diff --git a/drivers/media/dvb/pluto2/pluto2.c b/drivers/media/dvb/pluto2/pluto2.c index 598eaf8..80d14a0 100644 --- a/drivers/media/dvb/pluto2/pluto2.c +++ b/drivers/media/dvb/pluto2/pluto2.c @@ -439,7 +439,7 @@ static inline u32 divide(u32 numerator, u32 denominator) if (denominator == 0) return ~0; - return (numerator + denominator / 2) / denominator; + return DIV_ROUND_CLOSEST(numerator, denominator); } /* LG Innotek TDTE-E001P (Infineon TUA6034) */ -- cgit v1.1
