Removed: block comments trailing without separate line,
missing blanks after decarations, comparasion to NULL, assignment in if
condition, not necessary spaces after a casts, multiple assignments, line
over 80 characters, alignment not matched to open parenthesis, kmalloc with
multiplying instead kmalloc_array.

It is not appropriate to submit net-next changes at this time.

If you wish to contribute to the networking kernel code, you should
read the netdev mailing lists, and read important announcements such
as this:

THanks.
