Fix few trivial code style issues, pointed out by checkpatch, so they do
not get copied to new code (when old code is used as template):

  WARNING: Prefer "GPL" over "GPL v2" - see commit bf7fbeea ("module: Cure the MODULE_LICENSE "GPL" vs. "GPL v2" bogosity")
  WARNING: function definition argument 'struct platform_device *' should also have an identifier name
  ERROR: code indent should use tabs where possible
  WARNING: please, no spaces at the start of a line
  WARNING: Missing a blank line after declarations
  WARNING: unnecessary whitespace before a quoted newline
