The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 4387b3dbb079d482d3c2b43a703ceed4dd27ed28 Mon Sep 17 00:00:00 2001 From: Brant Merryman Date: Fri, 26 Jun 2020 04:22:58 +0000 Subject: USB: serial: cp210x: enable usb generic throttle/unthrottle 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.
