From dfa5ec79d28300b0d1fdeafbeebf0a6b721edc38 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 4 Mar 2008 15:25:11 -0800 Subject: USB: use DIV_ROUND_UP The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. An extract of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @haskernel@ @@ #include @depends on haskernel@ expression n,d; @@ ( - (n + d - 1) / d + DIV_ROUND_UP(n,d) | - (n + (d - 1)) / d + DIV_ROUND_UP(n,d) ) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP((n),d) + DIV_ROUND_UP(n,d) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP(n,(d)) + DIV_ROUND_UP(n,d) // Signed-off-by: Julia Lawall Signed-off-by: Andrew Morton Signed-off-by: Greg Kroah-Hartman --- drivers/usb/serial/io_ti.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/usb/serial/io_ti.c') diff --git a/drivers/usb/serial/io_ti.c b/drivers/usb/serial/io_ti.c index 39d71fdb5071..6afee30a6a5c 100644 --- a/drivers/usb/serial/io_ti.c +++ b/drivers/usb/serial/io_ti.c @@ -654,7 +654,7 @@ static void TIChasePort(struct edgeport_port *port, unsigned long timeout, int f /* (TIIsTxActive doesn't seem to wait for the last byte) */ if ((baud_rate=port->baud_rate) == 0) baud_rate = 50; - msleep(max(1,(10000+baud_rate-1)/baud_rate)); + msleep(max(1, DIV_ROUND_UP(10000, baud_rate))); } static int TIChooseConfiguration (struct usb_device *dev) -- cgit v1.2.2
