Merge branch 'sctp-endianness-fixes'
Xin Long says:
====================
sctp: a bunch of fixes for some sparse warnings
As Eric noticed, when running 'make C=2 M=net/sctp/', a plenty of
warnings or errors checked by sparse appear. They are all problems
about Endian and type cast.
Most of them are just warnings by which no issues could be caused
while some might be bugs.
This patchset fixes them with four patches basically according to
how they are introduced.
