fix coding style errors found by checkpatch:
- assignments in if conditions
- braces {} around single statement blocks
- no spaces after commas
- printks without KERN_*
- lines longer than 80 characters
- spaces between "type *" and variable name

before: 192 errors, 561 warnings, 8987 lines checked
after: 1 errors, 38 warnings, 9468 lines checked
