This is a note to let you know that I have just added a patch titled USB: option: reduce interrupt-urb logging verbosity to the linux-3.13.y-queue branch of the 3.13.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11.8. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From ef3a118f76601a84664f1274a6d7eb53732e9287 Mon Sep 17 00:00:00 2001 From: Johan Hovold <johan@kernel.org> Date: Tue, 29 Jul 2014 14:14:55 +0200 Subject: USB: option: reduce interrupt-urb logging verbosity commit f0e4cba2534cd88476dff920727c81350130f3c5 upstream. Do not log normal interrupt-urb shutdowns as errors. The option driver has always been logging any nonzero interrupt-urb status as an error, including when the urb is killed during normal operation. Commit 9096f1fbba91 ("USB: usb_wwan: fix potential NULL-deref at resume") moved the interrupt urb submission from port probe and release to open and close, thus potentially increasing the number of these false-positive error messages dramatically.
