This is a note to let you know that I have just added a patch titled usb: serial: silence all non-critical read errors to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt11. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 32ba655b6081ff30cce0ac697b2acad805861371 Mon Sep 17 00:00:00 2001 From: Jeremiah Mahler <jmmahler@gmail.com> Date: Sun, 11 Jan 2015 05:42:06 -0800 Subject: usb: serial: silence all non-critical read errors commit aa8e22128b40590b291cd13512098bf258a7e6c5 upstream. If a USB serial device is unplugged while there is an active program using the device it may spam the logs with -EPROTO (71) messages as it attempts to retry. Most serial usb drivers (metro-usb, pl2303, mos7840, ...) only output these messages for debugging. The generic driver treats these as errors. Change the default output for the generic serial driver from error to debug to silence these non-critical errors.
