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/tda10021.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/media/dvb/frontends/tda10021.c') diff --git a/drivers/media/dvb/frontends/tda10021.c b/drivers/media/dvb/frontends/tda10021.c index f5d7b32..6c1dbf9 100644 --- a/drivers/media/dvb/frontends/tda10021.c +++ b/drivers/media/dvb/frontends/tda10021.c @@ -176,7 +176,7 @@ static int tda10021_set_symbolrate (struct tda10021_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 = (((XIN << 5) / symbolrate) + 1) / 2; -- cgit v1.1
