[ofa-general] [PATCH] Non-supported functions should return NULL when returning pointers

[Jon Mason]

From: Jon Mason <jon at opengridcomputing.com>

Non-supported functions should return NULL when returning pointers.
Some/Most user space programs will not check for a (void *) to -ENOSYS,
which can look like a real address until referenced.

This patch converts the uses of (void *) -ENOSYS to NULL.
