Subject[PATCH] mISDN: suppress compiler warning
From
Date
Building the hfcpci driver triggers this GCC warning:
drivers/isdn/hardware/mISDN/hfcpci.c:2298:2: warning: ignoring return value of 'driver_for_each_device', declared with attribute warn_unused_result [-Wunused-result]

That return value is apparently ignored because _hfcpci_softirq() will
always return 0. Suppress this warning in the way a few other drivers do
that too.

0) I noticed this warning while building v3.6-rc6 on current Fedora 17,
using Fedora's default config.

1) Compile tested only.
