Subject: [PATCH -net] dccp: add do-while-0 stubs for dccp_pr_debug macros
Date: Sun, 08 Aug 2021 23:04:40 +0000 [thread overview]
Message-ID: <20210808230440.15784-1-rdunlap@infradead.org> (raw)
GCC complains about empty macros in an 'if' statement, so convert
them to 'do {} while (0)' macros.
Fixes these build warnings:
net/dccp/output.c: In function 'dccp_xmit_packet':
../net/dccp/output.c:283:71: warning: suggest braces around empty body in an 'if' statement [-Wempty-body]
283 | dccp_pr_debug("transmit_skb() returned err=%d\n", err);
net/dccp/ackvec.c: In function 'dccp_ackvec_update_old':
../net/dccp/ackvec.c:163:80: warning: suggest braces around empty body in an 'else' statement [-Wempty-body]
163 | (unsigned long long)seqno, state);
Fixes: dc841e30eaea ("dccp: Extend CCID packet dequeueing interface")
Fixes: 380240864451 ("dccp ccid-2: Update code for the Ack Vector input/registration routine")
