dccp: fix warning in net/dccp/options.c
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 <mingo@elte.hu> Signed-off-by: David S. Miller <davem@davemloft.net>
