From ba6c4033b9db22cb54e7e03dae5b624b7b0ffaf9 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 6 Jan 2009 14:42:25 -0800 Subject: drivers/rtc: correct an error test rtc is clearly does not satisfy IS_ERR at the point where it is tested, so I have changed the test to consider the just initialized rtc->rtc_dev. The semantic match that finds the problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // @match exists@ expression x, E; identifier fld; position p1,p2; @@ ( x = E; | x = E | x@p1->fld ... when != x = E IS_ERR(x@p2) ... when any ) @other_match exists@ expression match.x, E1, E2; position match.p1,match.p2; @@ x = E1 ... when != x = E2 when != x@p1 x@p2 @ script:python depends on !other_match@ p1 << match.p1; p2 << match.p2; @@ print "* file %s dereference %s test %s" % (p1[0].file,p1[0].line,p2[0].line) // Signed-off-by: Julia Lawall Acked-by: Alessandro Zummo Cc: David Brownell Cc: Bryan Wu Cc: Mike Frysinger Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- drivers/rtc/rtc-bfin.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/rtc/rtc-bfin.c') diff --git a/drivers/rtc/rtc-bfin.c b/drivers/rtc/rtc-bfin.c index 34439ce3967e..aafd3e6ebb0d 100644 --- a/drivers/rtc/rtc-bfin.c +++ b/drivers/rtc/rtc-bfin.c @@ -390,7 +390,7 @@ static int __devinit bfin_rtc_probe(struct platform_device *pdev) /* Register our RTC with the RTC framework */ rtc->rtc_dev = rtc_device_register(pdev->name, dev, &bfin_rtc_ops, THIS_MODULE); - if (unlikely(IS_ERR(rtc))) { + if (unlikely(IS_ERR(rtc->rtc_dev))) { ret = PTR_ERR(rtc->rtc_dev); goto err_irq; } -- cgit v1.2.3
