[ofa-general] [PATCH 1/6] IB/ipath - misc sparse cleanup

[Ralph Campbell]

From: Arthur Jones <arthur.jones at qlogic.com>

Recent sparse versions knock down the
false positive rate of the ipath driver
code to a point where having it be sparse
clean is worthwhile.  Here we fixup the
sparse warnings.  Some of these warnings
(and the impetus to run sparse again) are
due to work by Roland Dreier.
