Variable 'ret' is set to zero but this value is never read as it is overwritten with a new value later on, hence it is a redundant assignment and can be removed. Cleans up the following clang-analyzer warning: drivers/net/tun.c:3008:2: warning: Value stored to 'ret' is never read [clang-analyzer-deadcode.DeadStores] Reported-by: Abaci Robot <abaci@linux.alibaba.com> Signed-off-by: Yang Li <yang.lee@linux.alibaba.com> --- drivers/net/tun.c | 1 - 1 file changed, 1 deletion(-)
