Subject: [PATCH 3/6] USB: serial: cp210x: clean up control-request timeout
Date: Fri, 2 Jul 2021 15:42:24 +0200 [thread overview]
Message-ID: <20210702134227.24621-4-johan@kernel.org> (raw)
In-Reply-To: <20210702134227.24621-1-johan@kernel.org>
For consistency use the USB_CTRL_GET_TIMEOUT define for the
read-register request timeout (same value as USB_CTRL_SET_TIMEOUT).
