Subject: [PATCH 4.4 22/31] dccp: add do-while-0 stubs for dccp_pr_debug macros
Date: Tue, 24 Aug 2021 13:07:34 -0400	[thread overview]
Message-ID: <20210824170743.710957-23-sashal@kernel.org> (raw)
In-Reply-To: <20210824170743.710957-1-sashal@kernel.org>

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit 86aab09a4870bb8346c9579864588c3d7f555299 ]

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")
