Subject: [PATCH v1 04/10] PCI: qcom: do not duplicate qcom_pcie_cfg fields in qcom_pcie struct
Date: Thu,  2 Dec 2021 17:17:20 +0300	[thread overview]
Message-ID: <20211202141726.1796793-5-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20211202141726.1796793-1-dmitry.baryshkov@linaro.org>

In preparation to adding more flags to configuration data, use struct
qcom_pcie_cfg directly inside struct qcom_pcie, rather than duplicating
all its fields. This would save us from the boilerplate code that just
copies flags values from one sruct to another one.
