According to the kernel's coding style, the binary operator & should
have a space on each side.

Quoting documentation:

  Clean-up patches
  ~~~~~~~~~~~~~~~~
  
  Netdev discourages patches which perform simple clean-ups, which are not in
  the context of other work. For example:
  
  * Addressing ``checkpatch.pl``, and other trivial coding style warnings
  * Addressing :ref:`Local variable ordering<rcs>` issues
  * Conversions to device-managed APIs (``devm_`` helpers)
  
  This is because it is felt that the churn that such changes produce comes
  at a greater cost than the value of such clean-ups.
  
  Conversely, spelling and grammar fixes are not discouraged.
