Subject: [PATCH v4 11/38] platform/x86: intel_scu_ipc: Drop intel_scu_ipc_raw_command()
Date: Tue, 21 Jan 2020 19:00:47 +0300 [thread overview]
Message-ID: <20200121160114.60007-12-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20200121160114.60007-1-mika.westerberg@linux.intel.com>
There is no user for this function so we can drop it from the driver.
