1* checkpatch fixes
2* remove unnecessary comments
3* remove unnecessary error messages. Example kzalloc() has its
4  own error message. Adding an extra one is useless.
5* use goto statements for error handling when appropriate
6* there is a lot of unnecessary code in the driver. It was
7  originally a standalone driver. Remove uneeded code.
