Subject: [net-next 4/4] can: proc: fix rcvlist_* header alignment on 64-bit system

From: Erik Flodin <erik@...din.me>

Before this fix, the function and userdata columns weren't aligned:
  device   can_id   can_mask  function  userdata   matches  ident
   vcan0  92345678  9fffffff  0000000000000000  0000000000000000         0  raw
   vcan0     123    00000123  0000000000000000  0000000000000000         0  raw

After the fix they are:
  device   can_id   can_mask      function          userdata       matches  ident
   vcan0  92345678  9fffffff  0000000000000000  0000000000000000         0  raw
   vcan0     123    00000123  0000000000000000  0000000000000000         0  raw
