- Remove spaces before commas in _sock_locks macro definition
- Use tabs instead of spaces for macro line continuation indentation
- Separate assignment from if condition in __sk_receive_skb function
- Fix pointer declaration format in timer functions
- Add spaces around == operator in preprocessor directive

These changes improve code style compliance with kernel coding standards
without affecting functionality.
