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.

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