nfit: acpi_nfit_ctl(): Check out_obj->type in the right place
In the case of ND_CMD_CALL, we should also check out_obj->type. The patch uses out_obj->type, which is a short alias to out_obj->package.type. Fixes: 31eca76ba2fc ("nfit, libnvdimm: limited/whitelisted dimm command marshaling mechanism") Cc: <stable@vger.kernel.org> Signed-off-by: Dexuan Cui <decui@microsoft.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
