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/video/tuner-core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'drivers/media/video/tuner-core.c') diff --git a/drivers/media/video/tuner-core.c b/drivers/media/video/tuner-core.c index 537594211a9..2816f183923 100644 --- a/drivers/media/video/tuner-core.c +++ b/drivers/media/video/tuner-core.c @@ -819,8 +819,8 @@ static int tuner_g_frequency(struct v4l2_subdev *sd, struct v4l2_frequency *f) fe_tuner_ops->get_frequency(&t->fe, &abs_freq); f->frequency = (V4L2_TUNER_RADIO == t->mode) ? - (abs_freq * 2 + 125/2) / 125 : - (abs_freq + 62500/2) / 62500; + DIV_ROUND_CLOSEST(abs_freq * 2, 125) : + DIV_ROUND_CLOSEST(abs_freq, 62500); return 0; } f->frequency = (V4L2_TUNER_RADIO == t->mode) ? -- cgit v1.2.3
