Subject: [PATCH AUTOSEL 5.0 04/99] acpi/nfit: Always dump _DSM output payload

From: Dan Williams <dan.j.williams@...el.com>

[ Upstream commit 351f339faa308c1c1461314a18c832239a841ca0 ]

The dynamic-debug statements for command payload output only get emitted
when the command is not ND_CMD_CALL. Move the output payload dumping
ahead of the early return path for ND_CMD_CALL.

Fixes: 31eca76ba2fc9 ("...whitelisted dimm command marshaling mechanism")
