Hi,
This patch series is about to add a sysfs attribute, through which users can disable or enable USB3 LPM (link power management) from a USB port. Once LPM is disabled from the USB port, LPM between the downstreaming device and the hub port will not be activated. This helps users to use any LPM-unfriendly USB devices on any released Linux kernels.
This patch series contains a fix and a cleanup as well.
Change log: v2->v3: Make the code more readable by adding some comments and refactoring the "if/else" code.
v1->v2: Fix the "make htmldoc" warning reported by 0-day robot.
Thanks, Baolu
