From: Ian Munsie <imunsie@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@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.
