Subject: [PATCH v3 06/11] tools/testing/nvdimm: Prepare nfit_ctl_test() for ND_CMD_CALL emulation
Date: Mon, 20 Jul 2020 15:07:57 -0700
Message-ID: <159528287703.993790.423533202598012793.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <159528284411.993790.11733759435137949717.stgit@dwillia2-desk3.amr.corp.intel.com>

In preparation for adding a mocked implementation of the
firmware-activate bus-info command, rework nfit_ctl_test() to operate on
a local command payload wrapped in a 'struct nd_cmd_pkg'.
