Minor ./net cleanups - no functional changes - change #ifdef DEBUG printf(); #endif to just debug() - changed __FUNCTION__ to __func__ - got rid of extra whitespace between function and opening brace - removed unnecessary braces on if statements gcc dead code elimination should make this functionally/size equivalent when DEBUG is not defined. (confirmed on Blackfin, with gcc 4.3.3). Signed-off-by: Robin Getz <rgetz@blackfin.uclinux.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
