Subject: [PATCH v3 3/7] Bluetooth: hci_qca: provide default device data
Date: Tue, 22 Jun 2021 01:31:37 +0300	[thread overview]
Message-ID: <20210621223141.1638189-4-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210621223141.1638189-1-dmitry.baryshkov@linaro.org>

In order to simplify probe function provide default device data. This
removes the rest of if (data) checks.
