Subject: [PATCH 02/12] usb: dwc3: qcom: Rename dwc3 platform_device reference
Date: Mon, 16 Oct 2023 20:11:10 -0700	[thread overview]
Message-ID: <20231016-dwc3-refactor-v1-2-ab4a84165470@quicinc.com> (raw)
In-Reply-To: <20231016-dwc3-refactor-v1-0-ab4a84165470@quicinc.com>

In preparation for the introduction of a direct reference to the struct
dwc3 in the dwc3_qcom struct, rename the generically named "dwc3" to
reduce the risk for confusion.

No functional change.
