Subject: [PATCH v3 1/2] USB: serial: cp210x: Enable usb generic throttle/unthrottle
Date: Fri, 26 Jun 2020 04:22:58 +0000 [thread overview]
Message-ID: <57401AF3-9961-461F-95E1-F8AFC2105F5E@silabs.com> (raw)
From: Brant Merryman <brant.merryman@silabs.com>
Assign the .throttle and .unthrottle functions to be generic function
in the driver structure to prevent data loss that can otherwise occur
if the host does not enable USB throttling.
