tlan: Code cleanup: checkpatch.pl is relatively happy now.
- Remove CamelCase. - Convert hexadecimals to lower case. - Remove useless comments. Tlan driver contained a name of the function at the end of it in a comment. Remove those comments. - Remove local typedefs. Use real types instead of typedefs in code. - Resolve space issues and reindent. - One warning remain, it's a case where printing a single line involves a number of printk()s.
