Subject: [PATCH] drivers: staging: ft1000: Improve coding style
Improvements include:
- Lines over 80 characters;
- Use pr_info() instead printk(KERN_INFO);
- Removal of typedefs;
- Indentation.
- Fix IOCTL_FT1000_* marcos:
- Add closing brackets;
- remove sizeof (_IOR and _IOW macro can accept types);
- replace _IOW which size of 0 (the last arg) with _IO.
- Actually these macros are not used anywhere and might be removed.
