I am getting this compiler warning in linus tree :
CC [M] drivers/isdn/hardware/mISDN/hfcpci.o drivers/isdn/hardware/mISDN/hfcpci.c: In function ‘hfcpci_softirq’: drivers/isdn/hardware/mISDN/hfcpci.c:2333: warning: ignoring return value of ‘driver_for_each_device’, declared with attribute warn_unused_result
static void hfcpci_softirq(void *arg) { (void) driver_for_each_device(&hfc_driver.driver, NULL, arg, _hfcpci_softirq);
/* if next event would be in the past ... */ if ((s32)(hfc_jiffies + tics - jiffies) <= 0) hfc_jiffies = jiffies + 1; else hfc_jiffies += tics; hfc_tl.expires = hfc_jiffies; add_timer(&hfc_tl); }
It seems to me it should return is driver_for_each_device fails : if (driver_for_each_device(&hfc_driver.driver, NULL, arg, _hfcpci_softirq)) return;
or if possible can we return this error code for hfcpci_softirq()
Thanks, -- JSR
