Hello Alexander,
I passed chackpatch.pl to these files,
and found many things to fix.
I splitted the changes into a few different patches,
to make it easier for review.
Cheers,
Alex

This patch contains only trivial changes:
Some of them found with checkpatch.pl in strict mode.
- Remove trailing whitespace.
- Remove spaces coming before tabs.
- Fix typos in comments.
- Convert spaces into tabs.
- Add a space around operators that should have them,
and remove them when they shouldn't have them sround,
according to coding_style.rst.
- Use braces accordint to coding_style.rst.
- Align multi-line function prototypes, and other similar cases.
- Remove or add blank lines:
* Add blank lines after declarations, and before code.
* Remove blank lines after function definitions and before
EXPORT_SYMBOL().
- Remove redundant parentheses, when the don't improve readability.
- Fix comments' style according to coding_style.rst.
- Simplify comparisons against NULL, using '!' (or nothing at all).
- Use C89 comments (/* */), instead of C99 (//).

Slightly non-trivial changes:
- Move declarations to the top of function definitions.
- Split multiple assignments in a single line to
multiple lines with a signle assignment each.
