Subject: [PATCH v2 9/9] usb: dwc3: qcom: clean up suspend callbacks
Date:   Thu,  4 Aug 2022 17:10:01 +0200
Message-Id: <20220804151001.23612-10-johan+linaro@kernel.org>
In-Reply-To: <20220804151001.23612-1-johan+linaro@kernel.org>

Precedence: bulk

Clean up the suspend callbacks by separating the error and success paths
to improve readability.

Also drop a related redundant initialisation.
