Subject: [PATCH net-next 1/5] misdn: avoid -Wempty-body warning
From: Arnd Bergmann <arnd@...db.de>
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 */
Change this as suggested by gcc, which also fits the style of the
other conditions in this function.
