gcc warns about a pointless condition:
drivers/isdn/hardware/mISDN/hfcmulti.c: In function 'hfcmulti_interrupt':
drivers/isdn/hardware/mISDN/hfcmulti.c:2752:17: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
2752 | ; /* external IRQ */
As the check has no effect, just remove it.

v2: remove the line instead of adding {}

Thanks, interesting when we will delete whole drivers/isdn :)

Not any time soon I think, Harald Welte mentioned that Osmocom
still relies on mISDN.
The CAPI stuff only remains because of net/bluetooth/cmtp/ though.
I don't think there are any users, but Marcel wanted to keep cmtp
since it is not really hardware specific. We could probably move
drivers/isdn/capi/* to net/bluetooth/cmtp/ if there was a good reason.
