Subject: [PATCH v3 4/7] Bluetooth: hci_qca: merge qca_power into qca_serdev
Date: Tue, 22 Jun 2021 01:31:38 +0300	[thread overview]
Message-ID: <20210621223141.1638189-5-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210621223141.1638189-1-dmitry.baryshkov@linaro.org>

There is no need to allocate separate structure for handling regulators
used by QCA chips, we gain nothing from it. Move all used data fields
directly to struct qca_serdev.
