Subject: [PATCH v2 09/15] misc/mei/hdcp: Fix AUTH_STREAM_REQ cmd buffer len
Date: Tue, 20 Oct 2020 19:09:00 +0530	[thread overview]
Message-ID: <20201020133906.23710-10-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201020133906.23710-1-anshuman.gupta@intel.com>

Fix the size of WIRED_REPEATER_AUTH_STREAM_REQ cmd buffer size.
It is based upon the actual number of MST streams and size
of wired_cmd_repeater_auth_stream_req_in.
Excluding the size of hdcp_cmd_header.
