From: Ian Munsie on 3 Mar 2010 23:20 From: Ian Munsie <imunsie(a)au.ibm.com> The compiler throws the following warning during compilation: drivers/isdn/hardware/mISDN/hfcpci.c:2319: warning: ignoring return value of 'driver_for_each_device', declared with attribute warn_unused_result driver_for_each_device is being used to call _hfcpci_softirq for each device, which will only ever return 0. This patch explicitly ignores the return value to silence the warning. Signed-off-by: Ian Munsie <imunsie(a)au.ibm.com> --- Changes since v1: Changed name of dummy variable to hold unused return value from 'err' to 'dummy' as per Dan Carpenter's feedback. drivers/isdn/hardware/mISDN/hfcpci.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-) diff --git a/drivers/isdn/hardware/mISDN/hfcpci.c b/drivers/isdn/hardware/mISDN/hfcpci.c index 70e6b0e..ae50e5a 100644 --- a/drivers/isdn/hardware/mISDN/hfcpci.c +++ b/drivers/isdn/hardware/mISDN/hfcpci.c @@ -2316,7 +2316,8 @@ _hfcpci_softirq(struct device *dev, void *arg) static void hfcpci_softirq(void *arg) { - (void) driver_for_each_device(&hfc_driver.driver, NULL, arg, + int dummy; + dummy = driver_for_each_device(&hfc_driver.driver, NULL, arg, _hfcpci_softirq); /* if next event would be in the past ... */ -- 1.7.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
