Subject: [PATCH v2 15/17] media: cros-ec-cec: Use cros_ec_cmd()
Date: Wed,  5 Feb 2020 11:00:24 -0800	[thread overview]
Message-ID: <20200205190028.183069-16-pmalani@chromium.org> (raw)
In-Reply-To: <20200205190028.183069-1-pmalani@chromium.org>

Replace cros_ec_cmd_xfer_status() with cros_ec_cmd() which does the
message buffer setup and cleanup, but is located in platform/chrome
and used by other drivers.

Signed-off-by: Prashant Malani <pmalani@chromium.org>
Reported-by: kbuild test robot <lkp@intel.com>

Changes in v2:
- Updated to use new function name and parameter list.
- Used C99 element setting to initialize struct.
