- Clean up whitespaces, defines and variables.
- Remove obsolete code.
- Adhere to upstream coding style.
- Don't override returned error code.
- Replace pr_err with dev_err.
No functional changes are made by this patch. This is a minor code's refactoring that will ease further maintenance of the driver.
