[PATCH] Explicitly ignore unused return value of _hfcpci_softirq

From: imunsie

From: Ian Munsie <imunsie@xxxxxxxxxx>

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.
