[TRIVIAL] 2.5.31_drivers_char_lp.c

[Rusty Trivial Russell <rusty@rustcorp.com.au>]

[ As per 2.4.19 AC kernel tree, makes sense --RR ]
From:  Lucas Correia Villa Real <lucasvr@terra.com.br>

  Hi,
  
  This is a trivial patch already applied in the -ac tree for the 2.4.19 kernel.
  Patch for lp.c avoid +/- operations with 0 and explicit some debug information
  as KERN_INFO or KERN_ERR.
  
  Comments?
