====================
net: ipa: miscellaneous cleanups

This series contains some minor cleanups I've been meaning to get
around to for a while.  The first few remove the definitions of some
currently-unused symbols.  Several fix some warnings that are reported
when the build is done with "W=2".  All are simple and have no effect
on the operation of the code.
