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/frontends/ves1820.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media/dvb/frontends/ves1820.c') diff --git a/drivers/media/dvb/frontends/ves1820.c b/drivers/media/dvb/frontends/ves1820.c index 6e78e4865515..550a07a8a997 100644 --- a/drivers/media/dvb/frontends/ves1820.c +++ b/drivers/media/dvb/frontends/ves1820.c @@ -165,7 +165,7 @@ static int ves1820_set_symbolrate(struct ves1820_state *state, u32 symbolrate) tmp = ((symbolrate << 4) % fin) << 8; ratio = (ratio << 8) + tmp / fin; tmp = (tmp % fin) << 8; - ratio = (ratio << 8) + (tmp + fin / 2) / fin; + ratio = (ratio << 8) + DIV_ROUND_CLOSEST(tmp, fin); BDR = ratio; BDRI = (((state->config->xin << 5) / symbolrate) + 1) / 2; -- cgit v1.2.3
