Device interface coding style cleanup (dev.c, dev.h)

Device interface coding style cleanup (dev.c, dev.h)

According to Linux coding style:

- Don't use assignments in if statements.
- EXPORT_SYMBOL() has to follow directly it's function.
- Use the standard __func_ instead of gcc specific __FUNCTION__.
- Labels should not be indented.
- No braces should be put around single statements.
- Pointers have to be written as "foo *bar", not "foo * bar".
- Static data doesn't have to be initialized with 0.
