net: Remove redundant assignment to err
Variable 'err' is set to -ENOMEM but this value is never read as it is overwritten with a new value later on, hence the 'If statements' and assignments are redundantand and can be removed. Cleans up the following clang-analyzer warning: net/ipv6/seg6.c:126:4: warning: Value stored to 'err' 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> Signed-off-by: David S.
