From 3ed7cc0f8b29da4304825a7bcef25fc83f84c1ae Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Tue, 25 Nov 2008 16:57:30 -0800 Subject: [PATCH] dccp: fix warning in net/dccp/options.c MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit this warning: net/dccp/options.c: In function ‘dccp_parse_options’: net/dccp/options.c:67: warning: ‘value’ may be used uninitialized in this function is a bogus GCC warning. The compiler does not recognize the relation between "value" and "mandatory" variables: the code flow can ever reach the "out_invalid_option:" label if 'mandatory' is set to 1, and when 'mandatory' is non-zero, we'll always have 'value' initialized. Help out the compiler by annotating the variable. Signed-off-by: Ingo Molnar Signed-off-by: David S.
