This is a note to let you know that I have just added a patch titled USB: fix build error with CONFIG_PM_RUNTIME disabled 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 5af2beec977bb3a91a8bb36491524c433c03d0a0 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Date: Wed, 27 Aug 2014 16:55:29 -0700 Subject: USB: fix build error with CONFIG_PM_RUNTIME disabled commit a9ef803d740bfadf5e505fbc57efa57692e27025 upstream. commit bdd405d2a528 ("usb: hub: Prevent hub autosuspend if usbcore.autosuspend is -1") causes a build error if CONFIG_PM_RUNTIME is disabled. Fix that by doing a simple #ifdef guard around it.
