This patch fixed alignment, comment style and one appearance of
misordered constant in an if comparison.
Semantic should not be affected by this patch.
There are still a few warnings and even errors left which require
a semantic change of the code to fix.
e.g. use of in_atomic in drivers
There are also two warnings left about too long lines, which
reduce readability if changed.
