From: Arnd Bergmann <[email protected]> There are a couple of warnings in this driver when building with W=1: net/dccp/output.c: In function 'dccp_xmit_packet': net/dccp/output.c:283:71: error: suggest braces around empty body in an 'if' statement [-Werror=empty-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: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body] 163 | (unsigned long long)seqno, state); | ^ Change the empty debug macros to no_printk(), which avoids the warnings and adds useful format string checks.
