* checkpatch fixes * remove unnecessary comments * remove unnecessary error messages. Example kzalloc() has its own error message. Adding an extra one is useless. * use goto statements for error handling when appropriate * there is a lot of unnecessary code in the driver. It was originally a standalone driver. Remove uneeded code. Please send patches to Greg Kroah-Hartman <greg@kroah.com> and Cc: Lidza Louina <lidza.louina@gmail.com>
