Subject: [PATCH AUTOSEL 4.19 04/81] acpi/nfit: Always dump _DSM output payload
Date: Tue, 7 May 2019 01:34:35 -0400 [thread overview]
Message-ID: <20190507053554.30848-4-sashal@kernel.org> (raw)
In-Reply-To: <20190507053554.30848-1-sashal@kernel.org>
From: Dan Williams <dan.j.williams@intel.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")
