Subject: [PATCH v2 03/10] HID: intel-ish-hid: Simplify ishtp_cl_link()
Date: Mon, 18 Mar 2019 12:14:21 -0700 [thread overview]
Message-ID: <20190318191428.6527-4-srinivas.pandruvada@linux.intel.com> (raw)
In-Reply-To: <20190318191428.6527-1-srinivas.pandruvada@linux.intel.com>
All callers will only use ISHTP_HOST_CLIENT_ID_ANY, so get rid of
option to pass this additional id.
