Subject: nfit: acpi_nfit_ctl(): Check out_obj->type in the right place
Git-commit: 43f89877f26671c6309cd87d7364b1a3e66e71cf
Patch-mainline: v5.1-rc1
References: bsc#1129547

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")
