Patrick Pannuto 769b0796d5 checkpatch: Check for illegal return codes
The only legal integer return is 0, anything else
following "return" should be -ERRCODE or a function.

http://lkml.org/lkml/2010/7/23/318
  There's lots of "return -1;" statements in this patch - it's obscene
  that this is used to indicate "some error occurred" in kernel space
  rather than a real errno value - even when an existing function
  (eg, request_irq) gave you an error code already.

  Please note this for the future - and please review patches on this
  point internally first.
