[Qemu-devel] [PATCH 2/4] nvdimm: use *function* directly instead of allocating it again

[Wei Yang <richardw.yang@linux.intel.com>]

At the beginning or nvdimm_build_common_dsm(), variable *function* is
already allocated for Arg2.

This patch reuse variable *function* instead of allocating it again.
