Subject: [PATCH v3 16/20] firmware: add helper to check to see if fw cache is setup
Date:   Sat, 10 Mar 2018 06:14:57 -0800
Message-Id: <20180310141501.2214-17-mcgrof@kernel.org>
In-Reply-To: <20180310141501.2214-1-mcgrof@kernel.org>
References: <20180310141501.2214-1-mcgrof@kernel.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add a helper to check if the firmware cache is already setup for a device.
This will be used later.
