Subject: [PATCH iproute2-next 0/3] iplink_can: fix checkpatch.pl warnings

This is a clean up series which goes through all the checkpatch
warnings on ip/iplink_can.c and fixes them one by one. By the end on
this series, there is only one warning left:

  WARNING: Prefer __printf(2, 0) over __attribute__((format(printf, 2, 0)))
  #320: FILE: ip/iplink_can.c:320:
  +static void __attribute__((format(printf, 2, 0)))

Because iproute2 does not declare the __printf() macro, that last one
can not be fixed.
